Question

For a short magnet, the magnetic field on the axial line at a distance 10 cm from its centre is \( 1.6 \times 10^{-7} \, T \). What is the magnetic field on its equatorial line at the same distance 10 cm from its centre?

• A. \( 4.8 \times 10^{-7} \, T \)
• B. \( 3.2 \times 10^{-8} \, T \)
• C. \( 1.6 \times 10^{-7} \, T \)
• D. \( 0.8 \times 10^{-7} \, T \)

Hint:

Axial field is always twice the equatorial field for a short magnet.

Answer 1

The Correct Option is D
