Question

If a bar magnet of pole strength m and magnetid moment M is cut equally 4 times parallel to its axis and 3 times perpendicular to its axis then the pole strength and magnetic moment of each-piece are respectively (A) (m/20),(M/20) (B) (m/4),(M/20) (C) (m/6),(M/24) (D) (m/5),(M/4)

Tardigrade Admin · Accepted Answer

Correct answer is (c) (m/6),(M/24)

Q. If a bar magnet of pole strength m and magnetid moment M is cut equally 4 times parallel to its axis and 3 times perpendicular to its axis then the pole strength and magnetic moment of each-piece are respectively

$\frac{m}{20}, \frac{M}{20}$

$\frac{m}{4}, \frac{M}{20}$

$\frac{m}{6}, \frac{M}{24}$

$\frac{m}{5}, \frac{M}{4}$

Correct answer is (c) $\frac{m}{6}, \frac{M}{24}$

20m​,20M​

4m​,20M​

6m​,24M​

5m​,4M​

Correct answer is (c) 6m​,24M​

$\frac{m}{20}, \frac{M}{20}$

$\frac{m}{4}, \frac{M}{20}$

$\frac{m}{6}, \frac{M}{24}$

$\frac{m}{5}, \frac{M}{4}$

Correct answer is (c) $\frac{m}{6}, \frac{M}{24}$
