Question:medium

The radius of a coil of N turns is R. If the plane of the coil is placed parallel to a uniform magnetic field B, then the flux linked with the coil is

Show Hint

Be very careful with the angle in the magnetic flux formula. \(\theta\) is the angle between the B-field and the *normal* to the area, not the plane of the area itself. - If the plane is parallel to the field, \(\theta = 90^\circ\), and flux is zero. - If the plane is perpendicular to the field, \(\theta = 0^\circ\), and flux is maximum (\(NBA\)).
