Question

Consider a short magnetic dipole of magnetic length 10 cm. Its geometric length is

• A. 12 cm
• B. 8 cm
• C. 10 cm
• D. 14 cm

Answer 1

Answer: (A)

12 cm

Answer 2

Geometric length of a magnet is $\frac{6}{5}$ times its magnetic length.
$\therefore$ Geometric length $=\frac{6}{5}\times10$
$=12 \,cm$
