Question

If L be the length of a bar magnet then separation between the two poles is nearly (A) (9/10) L (B) (6/7) L (C) (1/3) L (D) (1/2) L

Geometric Length is always greater than magnetic length. The magnetic Length approximately 0.83 times to 0.85 times of geometrical length. So separation Between poles =(6/7) L.

Q. If $L$ be the length of a bar magnet then separation between the two poles is nearly

$\frac{9}{10} L$

$\frac{6}{7} L$

$\frac{1}{3} L$

$\frac{1}{2} L$

Geometric Length is always greater than magnetic length.
The magnetic Length approximately $0.83$ times to $0.85$ times of geometrical length.
So separation Between poles $= \frac{6}{7} L$ .
