why can’t we use magnetic brakes instead of friction brakes in cars

Couldn’t we just apply a magnetic force to the spinning wheel to slow it down?

The force of magnetic brakes is proportional to the speed of the vehicle. The brakes would be nearly worthless at low speed. You could make an active electromagnetic brake but it would be heavy and expensive and defeat the point of whatever you were trying to do with it.
