Is the refrigerator a magnet?
No- but if it has an electric motor (most do) the motor operates by use of an electromagnet. Many refrigerator door seals (not all) includes magnets.
Is the magnetic field of an electromagnet different to a bar magnet?
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.
How is a electromagnet diffrent then a permanent magnet?
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Is electromagnet a permanent magnet?
no
Is a horseshoe electromagnet bar magnet or a magnet pole a example of a temporary magnet?
An electromagnet is temporary because the field disappears when the current is switched off.
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

Which is better a permanent magnet or an electromagnet?
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 type of magnet is created from an electromagnet?
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
How is a electromagnet diffrent then a permanent magnet?
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
Is the worlds biggest magnet a magnet or electromagnet?
the world is
What are different words that involve magnets?
Electromagnet Superconducting magnet Ferromagnetic Magnetic needle Magnetic compass magnetic field. Hydro magnet Gyro magnet
What is a magnet made by electric current?
An electromagnet.
