9. An apparatus comprising:
at least one memory;
machine-readable instructions; and
at least one processor circuit to execute the machine-readable instructions to:
cause a tank circuit of an induction heater to switch from oscillating at a fixed frequency to oscillating at a resonant frequency in response to signals output by a sense coil of the tank circuit, the sense coil to output the signals based on a magnetic field generated by a work coil of the tank circuit;
detect a change in the signals output by the sense coil in response to a presence of a work piece relative to the work coil; and
cause a power drive unit to modify a power output at the induction heater in response to the change in the signals output by the sense coil.
