A single-turn circular coil of 60-m diameter carries a direct current of 30 × 104 A. Assuming Laplace’s expression for the magnetising force due to a current element, determine the magnetising force at a point on the axis of the coil and 80 m from the coil. The relative permeability of the space surrounding the coil is unity.
