Name any four application of electromagnets?

1. Electric motors: Electromagnets are used in electric motors to convert electrical energy into mechanical energy, allowing the motor to generate motion.

2. Magnetic resonance imaging (MRI): Electromagnets are used in MRI machines to create a strong magnetic field that interacts with the body's tissues, allowing for detailed images to be produced.

3. Magnetic levitation trains: Electromagnets are used in magnetic levitation (maglev) trains to create a magnetic field that repels the train from the tracks, allowing for frictionless movement and high speeds.

4. Speakers: Electromagnets are used in speakers to convert electrical signals into sound waves by vibrating a diaphragm or cone.
