which magnet is used for industrial purpose,,permanent magnet or electromagnet
Answers
electromagnet is used in industrial purpose because it has high strengh and force of attraction in respect to bar magnet.
Here is your answer :
⇒ The permanent magnet does not have electric current flow through it.
⇒ Electromagnets are made by passing electric current through it.
⇒ The strength of the magnetic field in permanent magnets cannot be changed.
⇒ The strength of the electromagnets can be changed by changing the amount of current in the magnet.
⇒ The direction of the magnetic field cannot be changed.
⇒ The direction of magnetic field can be changed in electromagnets.
⇒ The polarity of permanent magnets cannot be changed.
⇒ The polarity of the electromagnets can be changed.
Thus electromagnet is better and hence used for industrial purposes!
