hold a piece of iron or magnesium up to it and if it attracts it is magnetic
The magnetic materials which can magnetise and de-magnetise easily are called "soft magnetic materials" example:-ferrites,iron-cobalt alloy. The magnetic materials which cannot magnetise and de-magnetise easily are called "hard magnetic materials" example:-aluminium(al),nickel-cobalt alloy.
Light bonuses of an object
Iron.
See whether that object can attract nickel,steel,and metal.
The easiest is to align the object with the earth's magnetic field and pound on it with a hammer, but this is slow. Another is to rub one pole of a magnet repeatedly in the same direction along it. The fastest is to place it inside an electromagnet solenoid and power the electromagnet from a DC power source.
The verb form for "magnet" is "magnetize."
The same way you prove anything else. You need to be clear on what you have and what you want. You can prove it directly, by contradiction, or by induction. If you have an object which is idempotent (x = xx), you will need to use whatever definitions and theorems which apply to that object, according to what set it belongs to.
Electromagnets are only magnetised while the electrical current is switched on.
an object moves
stroke it one vay repeatedly against a magnet
Yes, however the object must be a magnetiseable metal such as iron. To magnetise it you could use a permanent magnet and slide it along the metal pice in one direction several times. Than you pice of iron for example would be a permanent magnet. Another way of doing this is, if there is no permanent magnet available, is to use a SOLENOID. You could build yourself one: Check it out on the internet. This solenoid would make your pice of iron permanently magnetic with the use of ELECTRICITY. This shows that magnetism and electricity are closely related. GUD LUCK and I hope my answer helped you.
Ask him or her to prove it (and keep a silver object handy just incase they are telling the truth). It is very easy to claim to be anything, it is another matter entirely to prove it.
