The radius of a circular coil having 100 turns is 5 cm and a current of 0.5A is flowing through this coil. If it is placed in a uniform magnetic field of stregth 0.001 T, then what torque will act on the coil, when the plane of the coil is perpendicular to the magnetic field ?

Number of turns 100 <br> Current `I=0.5A` <br> Radius of the circular coil, `r=5 cm =5xx10^(-2)m` <br> `:.` Area of the coil, `A= pi r^(2)=3.14xx(5xx10^(-2))m^(2)` <br> Magnetic field intensity, `B=0.001T`. <br> Now torque on the current carrying coill due to magnetic field `tau =nBIAsin theta` <br> When the coil is perpendicular to the field `theta=0^(@)`. <br> `:.tau=0`
