PROPULSION APPARATUS

1 . A propulsion apparatus comprising:

first and second conducting wires arranged with an interval therebetween; and

a power supply configured to output an alternating current,

wherein the alternating current output from the power supply having a phase difference of 90 degrees is made to flow through the first and second conducting wires.

2 . The propulsion apparatus according to claim 1 , further comprising:

a divider configured to divide the alternating current output from the power supply into two currents; and

a phase shifter configured to apply the phase difference of 90 degrees between the two alternating currents divided by the divider.

3 . The propulsion apparatus according to claim 2 , further comprising:

a changeover switch configured to advance a phase of the alternating current flowing through the first conducting wire by 90 degrees ahead of the phase of the alternating current flowing through the second conducting wire or delay the phase of the alternating current flowing through the first conducting wire by 90 degrees behind the phase of the alternating current flowing through the second conducting wire.

4 . The propulsion apparatus according to claim 1 ,

wherein the first and second conducting wires are each bundled in a coil shape.

5 . The propulsion apparatus according to claim 4 ,

wherein each of the first and second conducting wires includes a capacitor that performs LC resonance with inductance due to a structure with the coil shape at an output frequency of the power supply.

6 . The propulsion apparatus according to claim 4 ,

wherein each of the structure with the coil shape formed by the first conducting wire and the structure with the coil shape formed by the second conducting wire includes a magnetic core made of a magnetic material at a central axis.
