- Witricity, or wireless electricity, involves transferring electricity without wires through magnetic induction between two coils. - Originally demonstrated in the 1960s, MIT researchers recently redesigned experiments done by Nikola Tesla in the late 1800s to transfer electricity wirelessly in a safer way. - Witricity works by using an oscillating magnetic field produced by an alternating current in one coil to induce an electric current in a second coil placed nearby, allowing electricity to be transmitted over short ranges of a few meters without wires.
