Question

State any two limitations for natural magnet

Answer 1

Limitations of natural magnets:

1. Limited number of uses as they cannot be turned into desired shape.

2.they have low magnetic field as compared to electromagnets.

3. The strength cannot be changed as per requirement.

4.They cannot be switched OFF or ON as per requirements.

Answer 2

Two limitations of natural magnets --
1) The magnetic property is fixed. We cannot increase or decrease it.
2) The polarity is fixed. The north pole and south pole remains as it is.But in electromagnets we can change polarity by reversing the flow of current.
