Magnet Fatigue
Cyclic stress that can crack a magnet over many pulses — the burner's binding magnet gate.
Repeated energising cycles fatigue a magnet's structure even when a single cycle is safe. For the burner's high-field plug coil, static loads are acceptable but cyclic fatigue is the binding engineering gate — a limit Kronos states openly.
Repeated energising cycles fatigue a magnet's structure even when a single cycle is well within limits, and for the burner's high-field plug coil that cyclic fatigue is the binding engineering gate. Kronos states it openly and closes it with a powered magnet test coil taken through many cycles at full field.
Common questions
The high-field plug coil is sound statically but cyclic fatigue at full field is infeasible on today's assumptions — the burner's binding magnet gate, closed by a powered test coil.
