What is an electromagnet? Why is it called a temporary magnet?
Answers
Answer:
Temporary magnets only retain their magnetism while near a permanent magnetic field or electric current. Thus, they require an external force to remain in its magnetised state. When the battery is connected to the coil, current flows through it. ... Thus, electromagnet is called a temporary magnet.
Answer:
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. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil.Temporary magnets only retain their magnetism while near a permanent magnetic field or electric current. Thus, they require an external force to remain in its magnetised state. When the battery is connected to the coil, current flows through it. ... Thus, electromagnet is called a temporary magnet.
