Strength of Magnetic Forces Quick Check
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? (1 point)
O If they produce the same strength magnetic force, then they must have the same number of turns in the wire.
• 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 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.
