By use of the method of few-body physics, we study the relations between the energy of ground state and the thickness of three-electron quantum disk in a magnetic field. As the thickness increases, the magic number angular momentum states of three-electron(i.e., the states of fractional quantum Hall effect) will be destroyed. The results show the thicknesses of quantum disks whose magic number angular momentum is destroyed decrease as the magnetic fields increase.
