Why does an electric motor change the polarity of its electromagnet? - why does my ovary hurt all the time
Why an electric motor to change the polarity of the electromagnets?
Be attracted to A. For every half-lap cars must be amended to Poland and repelled by the permanent magnet poles.
B. For each turn, change, a change of direction of current flow in alternating current.
C. Changes polarity to compensate for losses in the flow of current when the motor makes a full revolution.

Option A is correct. Since the end of
In turn, DC-motor, repulsion and opposite polarity
Win polarities, and causes the magnetic force
in turn, anchors, and this movement can be used
to do the job.
what he knows about "electromagnetic induction, AC 'and then' he will come to you:)
to an alternating current to produce slip rings and brushes are "like a tower used ..
