The magnetic moment of an iron bar is $M$ . It is now bent in such a way that it forms an arc section of a circle subtending an angle of $6 0^{\circ}$ at the centre. The magnetic moment of this arc section isNEET 2024 (Re-NEET)

Answer:

Solution:

$M = m \cdot L$
$Rθ = L$ $\frac{R π}{3} = L$ $R = \frac{3 L}{π}$ $M^{'} = m (2 R) sin 3 0^{\circ}$ $= m (2) \frac{3 L}{π} \times \frac{1}{2} = \frac{3}{π} m L = \frac{3 M}{π}$
