Magnets are use to pick up things, in electric motors, to hold things on a metal wall, and in MRI.
You would usually use a magnet, which is just called using a magnet.
Magnetic keepers can be thought of as materials that complete the magnetic circuit of the magnet. They do this by providing a paramagnetic link from one pole of the magnet to the other. That way the magnet can resist the effects of other magnetic fields that might tend to depolarize or demagnetize it.
One way to separate paperclips from pennies is to use a magnet. Paperclips are made of metal and will be attracted to the magnet, while pennies are not magnetic and will not be affected. Simply wave the magnet near the mixture to attract the paperclips.
When one pole of a magnet is brought near each end of a hanging magnet, the hanging magnet will experience a force due to the interaction between the magnetic fields. Depending on the orientation of the poles involved, the hanging magnet may be attracted towards the other magnet if opposite poles are facing each other, or repelled if like poles are facing each other.
The north pole of one magnet will be attracted to the south pole of another magnet due to their opposite polarities. Like poles repel each other, while opposite poles attract.
Turn it around and use the other end.
One could use a magnet to separate sewing pins from carpet. Using a magnet also eases pin clean up on other surfaces as well.
if you have a magnet and a magnetic matereal, rub the magnet from one end of it to the other. do this several times and it will eventualy be a magnet.
1. u get magnet 2) put next 2 other manget

it said i find you very attractive

When one end of the unmagnetized needle is in contact with a magnet, the magnetic field from the magnet induces magnetism in the needle. This results in the end of the needle touching the magnet becoming a magnetic pole, and the other end becoming an opposite pole. The opposite poles attract each other, causing the unmagnetized needle to attract another needle when in contact with a magnet.

One way to separate iron nails from copper tacks is to use a magnet. The iron nails will be attracted to the magnet, allowing you to easily separate them from the copper tacks.
If you take two magnets, you will notice that one end attracts one end of the other magnet and repels the other end. The opposite happens if you flip the other magnet over. It is possible to make an electromagnet by winding wire around a piece of metal. If you attach the wire to a battery it will attract one end of the magnet. If you attach the wire to the other end of the battery, it will attract the other end of the magnet.Also, with electricity, you can use a switch to change which end of the battery will go through which end of the wire. When the magnet comes close to the electromagnet, the motor throws a switch and suddenly the electromagnet repels the magnet. Part of the switch can be attached to the magnet. So motors work because electromagnets can both attract and repel.
