Q.

A square current carrying loop made of thin wire and having a mass m = 10 g can rotate without friction with respect to the vertical axis OO₁ , passing through the centre of the loop at right angles to two opposite sides of the loop. The loop is placed in a homogeneous magnetic field with an induction $B = 10^{- 1} T$ directed at right angles to the plane of the drawing. A current I = 2A is flowing in the loop. Find the period (in sec) of small oscillations that the loop performs about its position of stable equilibrium. (Round off your answer to nearest integer)

Detailed Solution

$T = 2 π \sqrt{\frac{I}{MB}}$

here $I = \frac{m}{4} \frac{l^{2}}{12} \times 2 + \frac{m}{4} \frac{l^{2}}{4} \times 2 = \frac{{ml}^{2}}{6}$

and

$M = l^{2} i$

$T = 2 π \sqrt{\frac{I}{MB}} = 2 π \sqrt{\frac{m}{6 iB}} = 2 π \sqrt{\frac{0.01}{6 \times 2 \times 0.1}} = 0.57 s$
