A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
A permanent magnet, like a refrigerator magnet, is an example of a non-electromagnet. It produces a magnetic field without the need for an electric current.
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
No, the refrigerator itself is not a magnet. However, the door of the refrigerator may have a magnetic strip to keep it closed.
An electromagnet is a temporary magnet created by passing an electric current through a coil of wire wrapped around an iron core. In a refrigerator, an electromagnet is used in the compressor motor to create a magnetic field that causes the motor to rotate and pump refrigerant through the system, helping to cool the refrigerator.
The magnetic domains in a refrigerator magnet are laid down in parallel strips. They are also re-curved back on themselves so that the back side of the magnet has both north and south poles. If you put two refrigerator magnets back-to-back and move them around a little, it won't take long for you to "feel" the strips of magnetism. The common bar magnet have two simple poles at the ends.
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
