Electromagnetism
The Metals which can have magnetic properties are:
*Iron
*steel - permanent magnet
*cobalt
*nickel
Making Electromagnets
you need:
*Iron Core
*Coil of wire
*Electricity
How to increase the strength of an electromagnets:
-Increase the current
-Increase the amount of Fe
-Increase the number of coils
Left Hand Rule
Force (N) = Magnetic flux density (Tesla) X current (Amps) X length (m)
F = BIL
