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.

An electromagnet is a temporary magnet created by passing an electric current through a coil of wire, while a refrigerator magnet is a permanent magnet that can hold items to a refrigerator or other magnetic surface without needing an electric current. Electromagnets can be turned on and off by controlling the electric current, while refrigerator magnets retain their magnetism without the need for an external power source.

What is an example of a non electromagnet?
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.
Is the refrigerator a magnet?
No, the refrigerator itself is not a magnet. However, the door of the refrigerator may have a magnetic strip to keep it closed.
How is a electromagnet and a refrigerator?
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.
Is the magnetic field of an electromagnet different to a bar magnet?
Yes, the magnetic field of an electromagnet is different from that of a bar magnet. An electromagnet's magnetic field can be turned on and off by controlling the electric current, whereas a bar magnet has a fixed magnetic field. Additionally, electromagnets can have stronger magnetic fields than bar magnets, depending on the current passing through the coil.
What is an advantage of using an electromagnet rather than a regular magnet?
One advantage of using an electromagnet over a regular magnet is its controllability. The strength of an electromagnet can be adjusted by varying the amount of current flowing through it, providing flexibility for different applications. Additionally, electromagnets can be turned on and off easily by controlling the flow of electricity.
Is a refrigerator magnet electromagnetic?
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
What is an example of a non electromagnet?

How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
Which is better a permanent magnet or an electromagnet?
electromagnet
How are the uses of an electromagnet different from those of a permanent bar magnet?
An electromagnet can be turned on and off by controlling the flow of electricity, making it more versatile for applications like cranes, speakers, and MRI machines. Permanent bar magnets have a constant magnetic field and are commonly used in compasses, refrigerator magnets, and electric motors.
What are different words that involve magnets?
