1. A magnet in my home is a refrigerator magnet and an electromagnet is the motor in my vacuum cleaner.
2. Electromagnets are preferred in the real world over permanent magnets because they can be turned on and off, their magnetic strength can be adjusted, and they are more versatile in their applications. Permanent magnets, on the other hand, have a fixed magnetic field strength and cannot be turned on or off.
