Magnets and electromagnets can both be used to pick up metal items like iron nails. although they are alike, there is a difference between magnets and electromagnets. an example of this is that increasing the current running through the electromagnet's wire will make it stronger. what is another difference? a)increasing the amount of wire loops will increase the strength of an electromagnet.
b)increasing the amount of wire loops will increase the strength of a magnet.
c)there is no other difference between electromagnets and magnets.
d)electromagnets are always stronger than regular magnets.
