Problem

A rectangular loop of sides

20\,\text{cm}\times10\,\text{cm}

having

50

turns carries a current of

5\,\text{A}

. It is placed in a uniform magnetic field of

0.30\,\text{T}

so that the angle between the field and the normal to the loop is

30^{\circ}

. Calculate the magnitude of the torque acting on the loop. (a)

1.50\,\text{N m}

(b)

0.75\,\text{N m}

(c)

1.30\,\text{N m}

(d)

0.375\,\text{N m}
