At the beginning there were doubts, followed by a series of revealing experiments.
This example was the first unipolar motor that I built in 2012. Even back then, I was concerned with the question of counter torque. Where is the counter torque?
This is about the direction of rotation depending on the polarity of the power supply. Is there any dependency?
Would it also work as a wagon wheel so that the magnet pulls itself forward?
Is it an unipolar motor, even if the magnet is fixed and the sliding contact moves?
Can the unipolar motor used as driving wheel?
Can an unipolar motor be improved by using a surrounding contact ring?
Can an electric arc also be used as a current contact?
Further questions about the distance of the current contact to the magnet or current supply outside the magnet, etc.
Can two magnetic rings act together on one axis?
Can a permanently connected wire also be used as a current contact?
Can an electric coil used instead of a permanent magnet?
Can a linear unipolar motor be built?
