PHXII04:MOVING CHARGES AND MAGNETISM

363060 A wire of length \(l\) is bent in the form of circular coil of some turns. A current, i flows through the coil. The coil is placed in a uniform magnetic filed, B. The maximum torque on the coil can be

1 \(\dfrac{i B l^{2}}{2 \pi}\)
2 \(\dfrac{i B l^{2}}{4 \pi}\)
3 \(\dfrac{2 i B l^{2}}{\pi}\)
4 \(\dfrac{i B l^{2}}{\pi}\)
PHXII04:MOVING CHARGES AND MAGNETISM

363061 A coil area \(100\;c{m^2}\) having 500 turns carries a current of 1\(mA\). It is suspended in a uniform magnetic field of induction \({10^{ - 3}}\;Wb/{m^2}\). Its plane makes an angle of \(60^{\circ}\) with the lines of induction. The torque acting on the coil is

1 \(2.5 \times {10^{ - 6}}Nm\)
2 \(2.5 \times {10^{ - 7}}Nm\)
3 \(2.5 \times {10^{ - 3}}Nm\)
4 \(5 \times {10^{ - 4}}Nm\)
