Presented is a novel magnetic field modulator made up of permanent magnets, and having a torsional electrostatically driven structure, which was fabricated by electrodeposition and released by KOH solution wet etching. The magnetic properties of the electrodeposited CoNiMnP micromagnets and the torsional angle with respect to the driving voltage of the microdevice have been measured, and the modulation of the magnetic field has been demonstrated. The low power consumption micromodulator, which can achieve a continuous torsional angle of 0°–18° and a pull‐in angle of 54.7°, has its own advantage over the traditional magnetic field modulating devices. The novel modulator has not only provided a more effective approach for magnetic field modulation, but also offered a torsional carrier actuator to be integrated with various functional materials or components in many applications.
