How do “levitating” light bulbs work?

In: Technology

Through magnetic fields.

Magnetism both allows the levitating as well as wireless energy transfer.

The are many ways to design them. Most need a way to prevent the bulb from escaping the magnetic field.

Magnets are there in the bulb and the base to hold them in place. Electricity can jump and doesn’t need direct contact. For example, moving your hand near a plasma ball lamp will change the flow of electricity. The light bulb gets enough electricity to glow without actually touching the base.
