A magnetic keyboard has a plurality of magnetic keyswitches, and each magnetic keyswitch include a base, a keycap, a supporting device, a magnetic component and a metal thin sheet. The base has at least one engaging structure and a hole. The supporting device has a first support, an end of the first support is movably connected to the engaging structure, and the other end of the first support is movably connected to the keycap. The first support has a magnet portion. The magnetic component is disposed on the base and functioned with the magnet portion to provide a recovering force to the keycap. The metal thin sheet is disposed under the base and has a bendable cantilever portion covering the hole. While the cantilever portion is bent by an external force, the magnetic component can be removed through the hole.
