How can you make a magnet using a magnet?

Answer 1

You can do it by:

1) Stroking -stronking an iron bar with one of a magnet in one direction will the iron bar into a weak but permanent object

2) Heating and hammering- take a steel bar, put it under a magnetic field. Hit and hammer it. We get a permanent magnet.

3)By using direct current-Put a steel bar into a solenoid. Turn on the power supply. Remove the steel bar and after a while it will be magnetised.

Answer 2

This is a pretty wide open question. Are you trying to magnetise a screwdriver or the like? Generally, if the item to be magnetised is a ferrous item that is a shaft (long and narrow) all you need do is stroke it along a good strong magnet. Wiha, a Germany tool company, makes a tool for this purpose. It has an opening for magnetising and another for demagnetising screwdrivers and the like.

A temporary magnetic charge can be applied by wrapping the shaft with conductive wire and applying a DC charge (you have probably seen the great big electromagnets used in junk yards and the like).

Most old style hardware stores or electronics stores can magnetise a screwdriver or the like if you carry it to them. These people will be happy to help you out and they will end up being real good friends when you need help.

Answer 3

Yes you can

No1. Get a magnet. The stronger the better. Rub the magnet up a piece of metal then when you get to the end take the magnet off the metal and take it back to the start making sure the magnet doesn't touch the metal. I don't really like this method as it takes a long time to get the metal to pick up anything decent.

No2. Get a magnet and let it stick to a piece of metal. The piece of metal will be weak but enough to make the needle on a compass move.

(Don't ruin a compass. Mine point south-west and it shouldn't do that...)

Answer 4

stroke a magnet over a magnet responsive metal 1,000's of times in the same direction.
