O How are electricity and magnetism related?

o How do you make an electromagnet? What can you do to increase its power?

o What is the difference between a bar magnet and an electromagnet?

Magnetism is the product of a moving charged particle. We can have electricity without magnetism but we can not have magnetism without electricity. An electro magnet is made so that we have a soft metal core and electricity around it. A bar magnet is a normal magnet in bar shape with permanent magnetism.
