Probably not. The magnetic monopole, as it is called, has never been observed. Some theories predict the possibility that they exist, though.
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.

You can magnetize a piece of steel or iron, by stroking it with one end of a magnet. Stroke in one direction only, lifting off and away between each stroke. This aligns the atoms in a regular direction, in the blank piece of steel.
You can remagnetize a magnet by rubbing a good magnet along the bad one. Do this a few times. Be sure to rub the magnet in only one direction.
One of the needles has become a magnet.
One end of any bar magnet will always point north. This end is called the north-seeking pole.
No, it does not. The strength is identical on each end.
The Magnet ended in 1940.
If they are the same, they repel, if different, they attract.
If opposite, they attract, if the same, they repel.
No, it will overheat and fail.
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.
