what is differential axle?
A differential axle transfers power from the differential to the wheel to make the wheels turn. A differential is an assembly of worm gears that transfers the power from the drive train (engine/transmission) to the axles.
Any sort of metal. Faraday Cage for instance. Something that encloses the signal and is conductive so the signals cant go through it.
Not sure - what do you mean by EMF? What do you mean by mobile? I use EMF for electro-motive force and mobile for anything thats moving so I really have difficulty seeing what you are after.
A diff is for turning the wheels at different rates for better and faster cornering
emf can be best blocked by a cement.ü
