Differentiate between permanent magnet and electromagnet.
Class 6
Answers
Answer:
The key difference between an electromagnet and a permanent magnet is that the electromagnet can have a magnetic field when an electric current flows through it and disappears when the flow of the current stops, while permanent magnets are made up of magnetic material that can be easily magnetized and can create its ...
Answer:
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.
