A bar magnet having a magnetic moment `vecM ` is cut into four pieces i.e., first cut in two pieces along the axis of the magnet and each piece is further cut into two pieces. Compute the magnetic momment of each piece .

Text Solution

Verified by Experts

Consider a bar magnet of magnetic moment `vec(M) ` . When a bar magnet first cut in two pieces along the axis, their magnetic moment is `(vec(M))/(2)`
Ther magnetic moment of each pieces is `(vec(M))/(4)`
Magnetic moment of each piece `vec(M)_("new") = (1)/(4) vec(M)`
