A magnet with moment M is given. If it is bent into a semicircular form, its new magnetic moment will be:

A straight steel wire of length l has a magnetic moment M. When it is bent in the form of a semi - circle its magnetic moment will be

A steel wire of length l has a magnetic moment M . It is then bent into a semicircular arc. The new magnetic moment is

A steel wire of length l has a magnetic moment M. It is bent into a semicircular arc. What is the new magnetic moment?

A steel wire of length l has a magnetic moment M. It is bent into a semicircular arc. What is the new magnetic moment?

A steel wire of length l has a magnetic moment M. It is bent into a semicircular arc. What is the new magnetic moment?

A wire of length l has a magnetic moment M. Another wire of same length and magnetic moment is taken and is bent into a semicircular arc. Find the ratio of magnetic moment of wire to that of the semicircular arc.
