Couldn’t you theoretically charge an electric vehicle by driving through magnetic fields?

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)?

No. Not in the way I think you are thinking. Moving through an EM field will take energy from the movement, not the field itself. therefore you cannot transfer energy to the car in this way. However, all electric cars can do this but they carry the magnetic field with them and they call it regenerative braking. This can only save some energy, it cannot be used to increase energy overall.

There are other wireless energy transfer methods that could be applied to electric cars on the road though.
