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 to use!
