I am having trouble understanding a process in the electric motor. using this website as a frame of reference (http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/mothow.html), as an electric current is passed into that magnetic field, shouldn't the current also be creating a magnetic field, and does that magnetic field interfere with the magnetic field already present? Also when the coil in the magnetic field begins spinning is that what is causing the change in magnetic flux? If so, as that flux is changing should a back emf be induced, and if so again through what medium does that back emf travel? Sorry for so many questions I appreciate any help.
