A circular loop of radius R carrying a current I is placed in a uniform magnetic field with its plane perpendicular to B. The force on the loop is :
A hypothetical magnetic field existing in a region is given by →B=B0→er where →er denotes the unit vector along the radial direction. A circular loop of radius a, carrying a current i, is placed with its plane parallel to the x - y plane and the centre at (0, 0, d). Find the magnitude of the magnetic force acting on the loop.
