yes
The power of the battery controlling it.
The more turns of wire in an electromagnet the stronger the magnetic field.
longer= stronger
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.
It's directly proportional.
A "speed" sensor can affect the shifting of the trans.A "speed" sensor can affect the shifting of the trans.
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
