hope it helps u dear..
Answer:
Explanation:
Difference Between Electromagnet and Permanent Magnet
Electromagnet
Permanent Magnet
The magnetic properties are displayed when current is passed through it
Magnetic properties exist when the material is magnetized
The strength is adjusted depending upon the amount of flow of current
The strength depends upon the nature of the material used in its creation
Removal of magnetic properties is temporary
Once magnetic properties is lost, it becomes useless
It requires a continuous supply of electricity to maintain its magnetic field.
It doesn’t require a continuous supply of electricity to maintain its magnetic field
It is usually made of soft materials
It is usually made of hard materials
The poles of this kind of magnet can be altered with the flow of current
The poles of this kind of magnet cannot be changed.
