Abstract
A rotating magnetic field results from the superposition of two magnetic fields oriented perpendicularly to each other, which vary sinusoidally with equal frequency, but with a phase difference, ideally of 90 degrees.
Keywords electromagnet alternating current choke capacitor phase difference

2 pairs of electromagnets create a horizontal and a vertical magnetic field respectively driven with alternating currents even a resister in the circuit of a horizontal field does
not create a rotating field the metal disk remains at rest yeah
the today that in the the the
resistance is replaced with the choke and the
current is turned on immediately but this
begins to rotate a sign that the magnetic field rotates clockwise
this the the joke is replaced with the
capacitor the
but
now the disk rotates counterclockwise this shows that the horizontal component of the magnetic field leads the vertical long this experiment can also be viewed as a model for an
AC motor
