Answer:
Electromagnets are soft iron cores that are made into magnets on passing an electric current through the coil surrounding them. A permanent magnet is something that is an innate ability of a magnet that continues to show magnetism even if it is removed from the magnetic field.
Are electromagnets permanent magnets?
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.
Difference between Permanent Magnet and Electromagnet
Permanent (Bar) Magnet
They are permanently magnetized.
These are usually made of hard materials.
Electromagnet
These are temporarily magnetized.
They are usually made of soft materials.
