A thin magnet of moment M is turned into an arc of 90 °. Then new magnetic moment
M’ = 2√2M / π
� A thin magnet of moment M is turned at mid point 90 °. Then new magnet moment
M’ = M / √2
� A thin magnet of moment M is turned into an arc of 60 °. Then new magnetic moment
M = 3M / π
�
A thin magnet of moment M is bent at mid point at angle 60 °. Then new magnetic moment. �
M’ = M / 2
