|The two magnetic poles
|North and south
|The three principal magnetic metals
|Iron, Nickel and Cobalt. Extra: sometimes steel as it is mixed with iron.
|How can non-magnetic metals be made magnetic
|By making all the electrons face the same way
|What do two poles that are the same do when they are brought together?
|What do two unlike poles do when they are put close together?
|Two ways in which you can increase the strength of an electromagnet?
|By increasing the voltage and the amount of coils around it
|What is good about electromagnets?
|That you can control them. Make them magnetic and non-magnetic when you want.
|One way an electromagnet can be used and why is it useful?
|In a scrap heap magnet to separate the magnetic and non-magnetic metals into two.
|One piece of evidence to prove that earth acts like a giant magnet.
|It has North and South and has a melted liquid core which contains iron (magnetic metal).
|What happens if a magnet is cut in half?
|The only difference is that it's made smaller but it will still have a north and a south
|Will a magnetised metal last long being magnetic if it has been made magnetic by another metal?
|It depends if the person has been rubbing the magnet for a long time and IN THE SAME DIRECTION all the time but it will probably not last long as the atoms will go back to their original position
