Normal things, even humans, can levitate if they are placed in a strong magnetic field. Although the majority of ordinary materials, such as wood or plastic, seem to be non-magnetic, they all exhibit very weak diamagnetism. Such materials can be levitated using magnetic fields of about 10 Tesla.
How do you levitate?
Levitation is accomplished by providing an upward force that counteracts the pull of gravity (in relation to gravity on earth), plus a smaller stabilizing force that pushes the object toward a home position whenever it is a small distance away from that home position.
Can electricity make you levitate?
Electrostatic levitation is the process of using an electric field to levitate a charged object and counteract the effects of gravity. ... Due to Earnshaw's theorem, no static arrangement of classical electrostatic fields can be used to stably levitate a point charge.
