A) Equal pole strength
B) Magnetic moment \[\frac{M}{4}\]
C) Magnetic moment \[\frac{M}{2}\]
D) Magnetic moment M
Correct Answer: C
Solution :
If pole strength, magnetic moment and length of each part are \[{m}',{M}'\]and \[{L}'\]respectively then \[{m}'=\frac{m}{2}\] \[{m}'=m\] \[{L}'=L\] \[{L}'=\frac{L}{2}\] \[\Rightarrow {M}'=\frac{M}{2}\] \[\Rightarrow {M}'=\frac{M}{2}\]You need to login to perform this action.
