Question

The magnetic field of a bar magnet spreads ___.

• A. for a finite region around the magnet
• B. across a country
• C. across the earth
• D. infinitely far

Answer 1

The correct option is D

infinitely far

Theoretically, the field of a magnet spreads infinitely far. But in a practical situation, we observe the strength of a magnet is effective up to a limited range. Though the field extends till infinity, it becomes weaker after the limit. Hence, it is not felt.
