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