Question

which devices use electromagnets? check all that apply. commutators cranes solenoids generators audio speakers motors

Explanation:

• Commutators work with electromagnets in electric - motors to reverse current direction.
• Cranes use electromagnets to lift and move heavy magnetic objects.
• Solenoids are coils of wire that act as electromagnets when a current is passed through them.
• Generators use electromagnetic induction, and electromagnets are part of their operation.
• Audio speakers use electromagnets to convert electrical signals into sound by interacting with a permanent magnet.
• Motors use electromagnets to convert electrical energy into mechanical energy.

Answer:

• commutators
• cranes
• solenoids
• generators
• audio speakers
• motors
