Question

a bar magnet of magnetic moment M is cut into two parts of equal length what is the magnetic moment of either part​

Answer 1

Magnetic moment (M) = mL

here, m is pole strength and L is length of bar magnet

so , upon cutting a bar magnet into two equal halves of same length

then, new length is L/2

there is no change in the value of m as pole strength depends on material only....which is same

so , new magnetic moment will be half of its original value....

hope it helps uh......
