What is magnetisum?

Magnetism is the force with which objects are attracted or repelled to one another. Usually these objects are metals such as iron. Every magnet has two poles. This is where most of its magnetic strength is most powerful. These poles are called north and south or north-seeking and south seeking poles. The poles are called this as when a magnet is hung or suspended the magnet lines up in a north - south direction. When the north pole of one magnet is placed near the north pole of another magnet, the poles are repelled. When the south poles of two magnets are placed near one another, they also are repelled from one another. When the north and south poles of two magnets are placed near one another, they are attracted to one another. The attraction repelling of two magnets towards one another depends on how close they are to each other and how strong the magnetic force is within the magnet. The further apart of the magnets are the less they are attracted or repelled to one another.


What if you placed an unknown object in front of a magnet and it repelled what material would it be made of?

It could be either iron, nickel, cobalt or iron(or some other variation with that stuff included)


Would an electromagnet be attracted to a magnet?

Yes electromagnet would be attracted to a magnet provided direct current flows through the coil ie when the electromagnet is activated. As unlike poles attract each other the magnet is to placed accordingly. Otherwise repulsion would take place.


Why does the needle of a compass point south when it's put on a bar magnet?

When a compass needle is placed near a bar magnet, it aligns itself with the magnetic field created by the magnet. The compass needle is a small magnet itself, with its north pole attracted to the south pole of the bar magnet and repelled by its north pole. If the compass needle points south, it indicates that the bar magnet's south pole is near the compass's north pole, demonstrating the fundamental property of magnetic attraction and repulsion. Thus, the orientation of the compass needle reflects the magnetic field direction of the bar magnet.


How can the size of an eletrical current be increased when a magnet has been placed in the circut?

move the magnet faster


How can you determine the magnet if you have one brass rod and another magnet in space?

Cut one in half, and see if the two bits attract or repel one another. If they do, you have cut the magnet. Otherwise the rod. If you are allowed other equipment, you don't need to cut anything. Make a coil, connect to a meter, and see which rod, when pushed in and out of the coil, induces a current.


How does a non magnetic material behave when a magnet is placed near?

A non-magnetic material will not be attracted to a magnet and will not exhibit any magnetic properties. It will not stick to the magnet or experience any noticeable changes in its behavior when the magnet is placed near it.


What happens when a compass is placed next to a electromagnet?

the arrow goes to the magnet


What happens if iron and tin pieces are placed near a magnet?

When iron and tin pieces are placed near a magnet, the iron will be attracted to the magnet due to its ferromagnetic properties. This means that iron can become magnetized and will move toward the source of the magnetic field. In contrast, tin is not ferromagnetic and will not be affected by the magnet; it will remain in its original position. Therefore, only the iron will exhibit a noticeable reaction to the magnet.


Is calcite attracted to a magnet?

No, calcite is not attracted to a magnet because it is not a magnetic mineral. Calcite is a non-magnetic mineral and will not exhibit any magnetic properties when placed near a magnet.


What happens if magnet is placed next to copper?

When a magnet is placed next to copper, the magnetic field of the magnet induces an electrical current in the copper due to electromagnetic induction. This effect is known as eddy currents, causing the copper to become magnetized temporarily.


What can you conclude if you place the north pole of a bar magnet near the pole of an unmarked magnet and they repel?

That you have placed the magnet towards the northern pole of the unmarked magnet. Like poles retract while opposite poles attract
