Question

The strength of the South pole of magnet is ____the strength of its North pole.

• A. greater than
• B. less than
• C. equal to
• D. twice

Answer 1

The correct option is C equal to

Strength of a magnet is highest at its poles. However, the strength is equal at both the poles.
This can be verified using two ways:
1. Iron filling experiment: The density of fillings is roughly the same at both the poles.
2. Deflection of compass: At same amount of distance from the magnet, same amount of deflection is observed in the compass.
