As far as my understanding goes it’s possible to create power with a magnet moving around a wire coil.
Couldn’t we use this effects and charge electrical vehicles by driving over magnets (most basic idea)?
In: Physics
As another poster said, the energy to charge the battery would come from the forwards motion of the car, and thus you would lose speed as you charged the battery, thus causing a net-negative kinda situation.
However, if you string overhead power lines over a train track, you can have the train touch those wires with a flexible connector and have 100% electric propulsion with theoretically infinite range and no batteries involved.
