Two electromagnets are made with the same core and same type of wire. Electromagnet he has a low intensity current, and electromagnet B has a high intensity current. Which statement about the electromagnet is correct?
If they produce the same strength magnetic force, then electromagnet A has more turns in the wire.
If they produce the same strength magnetic force, then they must have the same number of turns in the water.
If they have the same number of turns in the wire, and electromagnet a has a stronger magnetic force pot.
If they have the same number of of turns in the wire, then they must have the same strength magnetic force.
