    ive been doing some thinking to a question brought up by my advanced physics teacher...i can't really back up any of my responses though...any help on whether electricity and magnetism are more alike or different?

    You couldn't go far wrong saying "more alike." Your ammunition to back this up with is that both electric field components and magnetic field components are elements of the Faraday tensor. That means, given the rules for tensor transformation under a boost (which is just a way of saying calculated in two different reference frames, one moving at uniform velocity with respect to the other), that there will be a mixing of the electric and magnetic field components. So they really can't be all that different, eh?

    An electromagnet made of a battery, a wire and a nail will show the conection between electricity and magnetism.

    A strong magnet, a wire and an ammeter will show the connection between magnetism and electricity.
