Magnetism is an invisible force that attracts and repels certain objects with a magnet. Every magnet has a north and a south pole, and the opposite sides (north and south) attract. For example, if I took two magnets and pushed the north pole of one and the south pole of another towards each other, they would attract and stick together. Similarly, if i took the two magnets and pushed the two north sides or the south sides together, they would repel. One theory as to why this happens is that the magnetic field around the the magnets go in one end and out of the other. When the north and south poles are aligned properly, the magnetic fields will either bounce off of each other and repel or they will connect and attract towards each other.

Great work overall! Maybe you can explain more on why they sometimes bounce and why they sometimes attract each other? Nice job!

When the north and south poles are aligned properly, the magnetic fields will either bounce off of each other and repel or they will connect and attract towards each other. The fields will bounce off of each other because they are travelling in the same direction and will continuously hit each other. They will also attract as if the fields are travelling in opposite directions, they will catch on to each other and pull in towards one another.

Magnetism is the force of any object. Different objects have different amounts of magnets, and the more magnetism something has, the more "attraction" it has. For example, plastic objects, like bags, bottles, and containers, do not have as much magnetism as metal objects like magnets, steel poles, and aluminum.

Magnets have a south and a north side ; the magnetism path comes out form the north side and into the south side. When two magnets are facing each other with the same sides, the motion of the magnetic path bounces the magnets back, which causes the magnets to repel. However, when opposite sides are facing each other, the motion is the same, so it allows the field lines to line up and attract to each other.

Magnetism is a invisible magnetic force. It attracts and repels depending on which side the magnets are facing. A magnet has a north and south side. When the same sides are put together, the force goes the same way and it would bounce off each other, so they repel from each other. On the other hand, when different sides are put together, the force would hook on to each other since they go different ways, so they would attract.

Jeffrey

Your second sentence is a little confusing. Instead of saying "sides" or "goes", you could try using some more detailed words such as poles or direction.

Okay thanks.

Magnetism is a invisible magnetic force. It attracts and repels depending on which direction the magnets are facing. A magnet has a north and south side. When the same sides are put together, the force of each side would go in the same direction which causes it to bounce off each other, so they repel from each other. On the other hand, when different sides are put together, the force would hook on to each other since they travel towards each other, so they would attract.

Magnetism is a force that we can't see. Magnets have a North and South side. If the north side is facing South it would attract each other. If the south is facing South it would repell from each other. Some people think it plell becausee of the moving electrons inside. Lastly magnetism is magnets that can attract or repell.

Tyler

Magnetism is a force that you can't see, it has a North and a South side. Magnets can repel, and attracts. Opposites attract and simulars repel. I can't explain how magnetism works without a diagram.

Shirley

A magnetism is a objects that produce fields that attract or repel other objects. Every magnet have north and south side, when you put the magnet into same side it will repel each other. But, if you put it not in same side they will attract each other. So, if north and south side are facing together they will attract. It prove that if you north and north same side they will repel. That is how magnet attract and repel by using north side and south side.

Magnetism is an invisible rotation. Each magnet has a north and south pole. The opposite poles attract each other because the magnetic rotation collide into one another, making the two poles stick. On the contrary, when the two sides are the same, for instance a south pole and a south pole, the magnetic rotation smashes into each other, making the two side repel from one another.

Magnetism is the act of magnetic fields colliding. Two or more magnets attract or repel depending on the way they are facing. Each magnet has two poles, north and south. When two of the same poles are next to each other, they repel off of each other and push each other back. Likewise, when two of the different poles are next to each other, they attract and they stick together. One explanation of magnetism is that when the opposite poles are together, the electrons grab each other and pull themselves inward. Similarly, when two of the same poles are next to each other, they bounce off each other and repel themselves.

Magnetism is an invisible force. The magnets act when they are supposed to, for example, It depends that if the magnets are facing to the north or the south. There is one more thing, if something has a lot of magnetism for example a metal material, and the more magnetism it has the more attraction it has. If two magnets are facing the same side meaning if two magnets face each other in the north side then they will not attract they will repel. So this is called magnetism.

Magnetism is an invisible force that is all around us. It attracts or repels other magnetic objects depending on which side the magnet is facing. There are two magnetic sides on a magnet, these are called the north and south poles. If the north side is facing a south side, they will attract and vice versa. But if a north side is facing another north side, they will repel and vice versa. Though I don't really remember this theory very well, one explanation for the magnets behavior is that there is some useable "vacuum" of sorts around the magnets. If the north is facing the south, the vacuum would suck them together, essentially sticking them to one another. But if they are both north or south poles, the vacuum would try to blow the other away, repelling the magnet. Whether it is in your fridge magnet or in a door, magnetism is an important piece of science that has benefitted us greatly since its discovery.

Magnetism is an invisible force of any object. It repels and attracts with a magnet for certain objects. All objects have a magnetic field and some objects have more magnetic field than others. Magnets have a north and south side. When they meet the same side like North with North they repel and when they meet different side North with South they attract.

Magnetism is an invisible force that produce a magnetic field to attract or repel other magnetic object. All the object has a magnetic field even a piece of paper. Is just that their magnetic field is really weak so it couldn’t stick to a magnet or any metal items Every magnet has a north and south side. If the magnet face the same side like North to North, the magnets will repel. On the other hand, if they face a different way like North to South, the magnets will attract. This is basically how magnets work.

Magnetism is an invisible force that is produced by electric charges. It ends up in attracting and repelling forces in different objects. There are two sides of a magnet. A north side and a south side. When it's the same two sides, it repels (example: north; north) If one is north and one is south, it attracts. Opposite sides attract while same sides repel.

Magnetism is invisible magnetic fields colliding. It is produced from the movement of electric charge, followed by attracting and repelling forces. A theory is that magnets have an electric field around them, rotating in one direction. When two magnet's magnetic fields are moving in the same direction, they repel each other, and vice versa.

Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges.

Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. Spinning like Beyblades, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron to act like a microscopic magnet.

In most substances, equal numbers of electrons spin in opposite directions, which cancels out their magnetism. That is why materials such as cloth or paper are said to be weakly magnetic. In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic—but they are not yet magnets.

To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet. The magnetic field is the area around a magnet that has magnetic force.

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet.

Some substances can be magnetized by an electric current. When electricity runs through a coil of wire, it produces a magnetic field. The field around the coil will disappear, however, as soon as the electric current is turned off.

As earlier mentioned, all magnets have both a north and a south pole, which causes them to either repel or attract one another depending on how the two poles are lined up. If the north pole of one magnet meets the south pole of another, the two will be attracted, but if either both north or south poles meet, the magnets will repel one another. No matter what type of magnet, the opposite poles always attract while similar poles always repel. Each magnet sends out a magnetic field, which is positive on one pole and negative on the other. This magnetic field is the result of the movement of negatively charged electrons within the magnet. These fields are strongest directly at the pole, which is why the ends of magnets will so powerfully repel or attract each other.

Magnetism is an invisible force that can attract and repel things. Every single magnet have a north and south side, each side of those sides attracts the opposite and repels the same. The reason for this is because each side is like an invisible arm spinning in circles. North and south sides spin different directions. If you take 2 of the same sides they will spin in the same directions so they won’t get stuck together. But, if you take different sides, when they spin they will hit each other and end up getting stuck.

Magnetism is a force that is among most things that either attract or repel. They usually have one north side and one south side. Magnets can be used for fun and for experiments. Magnets have been used for compasses, motors, and even floating subways.
