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
