What are 5 examples of electromagnets?
Electromagnets are very widely used in electric and electromechanical devices, including:
- Motors and generators.
- Transformers.
- Relays.
- Electric bells and buzzers.
- Loudspeakers and headphones.
- Actuators such as valves.
- Magnetic recording and data storage equipment: tape recorders, VCRs, hard disks.

How do you make a project electromagnet?
Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail.
What is a good example of an electromagnet?
Examples of electromagnetic devices include doorbells and any devices that have electric motors, such as electric fans. The electromagnet in a doorbell attracts the clapper, which hits the bell and makes it ring.
