Abstract: A magnetic apparatus and a magnetic system are provided. The magnetic apparatus or the magnetic system includes the magnetic apparatus that can generate the mechanical torque and at least two magnetic apparatus are coupled together to sum each mechanical torque. In addition, a phase angle delay of each of the magnetic torque of the at least two magnetic apparatus is arranged to minimize a torque ripple so as to output a power smoothly.
