1. A method of manufacturing a rotor with directional magnetic field configured for use in an electric aircraft, the method comprising:
disposing a plurality of magnets within a magnet array;
the magnet array is configured to create a directional magnetic field, wherein the magnet array comprises a first side having a first magnetic field strength and a second side having a second magnetic field strength, wherein the first magnetic field strength is greater than the second magnetic field strength;
applying an electrically insulating epoxy to at least a segment of the magnet array; and
receiving a mandrel, wherein the mandrel comprises an electrically insulating material, wherein the mandrel is configured to surround at least a portion of the magnet array.
