A magnetic light-shielding apparatus includes a body, a light-shielding element and a magnetic actuator. The body has a light-penetrating portion, and one end of the light-shielding element is disposed pivotally on the body to form a rotation center. The light-shielding element corresponding to the light-penetrating portion rotates with respect to the rotation center. The magnetic actuator has a magnetic element, a magnetically conducting element and a coil. The magnetically conducting element is disposed with respect to the magnetic element. The coil is disposed at the other end of the light-shielding element and surrounds the magnetically conducting element.
