Abstract: A portable electronic device including a body, a stand, and first and second magnetic assemblies is provided. The stand is pivoted to the body to rotate and being opened or closed relative to the body. The first magnetic assembly having a first magnetic dipole is movably disposed in the body. The second magnetic assembly having a second magnetic dipole is disposed on the stand. When the stand is closed to the body, the first and second magnetic dipoles correspond to each other, and produce a first and second corresponding states. In the first corresponding state, magnetic poles with opposite polarities of the first and second magnetic dipoles correspond to and attract each other. In the second corresponding state, magnetic poles with the same polarity of the first and second magnetic dipoles correspond to and repel each other, and the stand is spread relative to the body due to the repulsion.
