Question

how can we magnetize an iron piece and test that it has been magnitize

Answer 1

heya friend...
.
your answer is as follows...
..
Rub the North pole from the middle of the metal to the end. With firm pressure, quickly run the magnet across the piece of metal. The act of rubbing the magnet across the metal helps the iron atoms align in one direction. Repeatedly stroking the metal gives the atoms more opportunity to line up.Repeat the stroke towards the negative pole at least ten times. Ten strokes is just a good number to start with. You can do more or less as long as the metal works to your satisfaction as a magnet...

Test the magnetism. Tap the metal against a pile of paperclips or try to stick it to your fridge. If the paperclips stick or it stays on the fridge, the metal has been sufficiently magnetized. If the metal does not become magnetized, keep rubbing the magnet in the same direction across the metal. If you are magnetizing a screwdriver, put it next to a screw to see if it holds it.

Answer 2

Take two iron pieces and rub against each other for a while. Now take one of the iron piece and keep it in a place surrounded with iron things such as iron filings, needle etc. You'll see it has magnetized.
