A de-icing system is provided that includes a member, a coil, and a power supply. The member includes an anti-icing portion. The coil is inductively coupled to the anti-icing portion of the member. The power supply is coupled to the coil, and is configured to provide voltage to the coil. The coil emits electromagnetic energy responsive to power supplied by the power supply. Responsive to the electromagnetic energy, eddy currents are generated in the anti-icing portion that provide heating of the anti-icing portion.
