An analysis is developed which expresses the average electromagnetic levitation force Fx on a spherical conductor in terms of the effective inductance L of the excitation coil. This force is given by Fx = ½ I02 (∂L/∂x) where I0 is the r.m.s. coil current and x is the separation of the coil and sphere.
