An electronic lock comprises a magnetic induction mechanism, a clutch mechanism, a lock core mechanism linked with one end of the clutch mechanism, and a rotation mechanism linked with other end of the clutch mechanism. The magnetic induction mechanism is formed of a permeable outer iron piece, a permeable inner iron piece, a permanent magnet located between the outer iron piece and the inner iron piece for generating an auxiliary magnetic field, and an induction coil held by the inner iron piece for generating an induction magnetic field. The clutch mechanism is activated by a combined force of the auxiliary magnetic field and the induction magnetic field.
