Electromagnetic force and vertiport for the same

A vertiport comprising:

• a main body;
• an elevating device configured to move up and down with respect to the main body;
• a take-off and landing portion disposed on an upper portion of the elevating device, wherein:
• the take-off and landing portion is configured to operate to allow an aircraft equipped with a magnet unit in a lower portion of a fuselage to take off, land, and move;
• the magnet unit comprises a plurality of permanent magnets;
• and
• the plurality of permanent magnets comprises a central magnet disposed in a center of the magnet unit and a peripheral magnet surrounding the central magnet;
• a coil unit disposed in the take-off and landing portion and configured to interact electromagnetically with the magnet unit of the aircraft, wherein:
• the coil unit comprises a plurality of coils disposed in a position corresponding to the plurality of permanent magnets;
• and
• the plurality of coils comprises a central coil disposed in a center of the coil unit and corresponding to the central magnet and a peripheral coil surrounding the central coil and corresponding to the peripheral magnet, wherein the peripheral coil comprises a plurality of electromagnetic coils disposed in a circular shape and surrounding the central coil;
• and
• a controller disposed in the elevating device and configured to apply a current to the plurality of coils, wherein the controller is configured to control a direction and an intensity of the current flowing through the plurality of coils.
