1. An optical element driving mechanism, comprising:
a movable part connecting an optical element;
a fixed part, wherein the movable part moves relative to the fixed part; and
a driving assembly driving the movable part to move relative to the fixed part,
wherein the driving assembly comprises:
a first magnetic element;
a second magnetic element;
a coil, wherein a first section of the coil corresponds to the first magnetic element, and a second section of the coil corresponds to the second magnetic element;
a first magnetic permeable element, corresponding to the first magnetic element; and
a second magnetic permeable element, corresponding to the first magnetic element, wherein the second magnetic permeable element moves relative to the first magnetic permeable element.
