    Abstract: A voice coil motor held immobile by magnetic attraction when not in use for photography purposes includes a base, a magnet fixed thereto, a carrier, a magnetic member, and a coil. The magnetic member is fixed to the carrier and is attracted by a permanent magnetic field (first MF) of the magnet on the base. The coil is fixed to the carrier and the magnetic member. When the voice coil motor is powered on, the coil generates a second magnetic field (second MF) opposing the first MF. The second MF reduces or eliminates the attractive force of the first MF of the magnet, to separate the carrier and its fittings and allow them to work freely. A lens module and an electronic device are further provided.
