摘要
A ring magnet (24) fastens in a casing (20a,20b). Induction coils (36a,36b) on a rotor (12) link to LEDs (38,40) so that, as the rotor turns at a satisfactory speed, a current induced in the induction coils causes the LEDs to light up after different levels of force exerted by a user. Three LEDs interlink in parallel on each induction coil.
