1. A magnetic coupling unit comprising:

  • one or more first magnetic devices each capable of being magnetically coupled with a second magnetic device in another magnetic coupling unit; and

    one or more coupling reinforcing sectionsinclude a first current generation section and a second current generation section electrically connected to each other, andwherein a flowing direction of a first current generated in the first current generation section is opposite to a flowing direction of a second current generated in the second current generation section,wherein a number of windings of a magnetic device of the second current generation section is more than a number of windings of a magnetic device of the first current generation section, andwherein an amount of the first current is larger than an amount of the second current, and a difference between the amount of the first current and the amount of the second current reinforce magnetic coupling.
