Q13. State the factors on which the strength of an electromagnet depends differentiate between
an electromagnet and permanent magnet.
Answers
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.

Answer:
Difference between Permanent Magnet and Electromagnet is magnetic field and strength. In Electromagnet, the magnetic field is created by a wire-wound coil but the magnetic field of Permanent (Bar) Magnet cannot be changed. The strength of Permanent Magnet depends on the material used for its creation, on the other hand, the strength of Electromagnet varies according to the flow of electric current into it. Three types of Permanent (Bar) Magnets are Ceramic Magnet, Flexible magnets, Neodymium iron boron magnet, and Samarium cobalt magnet. Each has its own applications and types.
