A new technology uses magnets to refill car batteries without the need to plug it in.

Researchers at the University of British Columbia have invented a method for wirelessly charging electric vehicles.

The technology uses two magnets. One rotating base magnet is set in a parking spot, drawing energy from the grid, and a second is installed in the vehicle. When the vehicle is in position the magnet in the car rotates because of the pull of the base magnet. This movement generates power to charge the battery.

Here’s a demonstration of the technology in action:

Lorne Whitehead, Professor of Physics at the University of British Columbia, whose team created the technology explained the benefits of their work:
