Question

how does the lenght of a magnet change its lenght?​

Answer 1

$answer$

Explanation:

Magnetic moment (M = M . 2l) becomes halved because, length is also halved. ... A bar magnet of magnetic moment M is cut into two parts of equal length.

Answer 2

Answer:

Magnetic moment (M = M . 2l) becomes halved because length is also halved. The pole strength of each piece when a bar magnet is cut into two equal halves perpendicular to its length is the same as the pole strength of the original bar magnet. A bar magnet of magnetic moment M is cut into two parts of equal length.
