a magnetic field is an invisible force that pushes / pulls on positively and negatively charged particles in opposite directions
an electrical current is a flow of electrons (negatively charged subatomic particles) through matter
because idk science or something electrical current creates a shifting magnetic field, and a shifting magnetic field creates electrical current
motors and generators work exactly the same but in reverse. every motor is actually also a generator (of course, you can minmax one way or the other so any motor is going to be a shit generator and vice versa)
because idk science or something current doesn't create a magnetic field straight forward though, it's rotated 90 degrees. so you get some funny shape combinations to get it to work
for example a coil of wire will create a linear magnetic field through the center of the coil, and vice versa
