So far i know electrons like to flow to the left when it is in a magnetic field and right when the field is reversed

Maybe a current source over a voltage source. That way the voltage differences can be seen by the op amp.

Will this work if i have a precisely cut bismuth square and the connection are on the perfect place?

Electrical and magnetic fields intersect perpendicular. electrons flow from - to + following the path of least resistance. i think hall sensors(light switch) just work off ir or a photodiode unless your talking about a hall effect sensor then idk. just tryin to put in my input not tryin to be a dbag ...

Make sure the sensor is measuring the motor and not the current going into motor.

I think you need a magnet on the motor shaft
