| 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.

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
00:18
not create a rotating field the metal disk remains at rest yeah
00:26
the today that in the the the
00:42
resistance is replaced with the choke and the
00:52
current is turned on immediately but this
00:59
begins to rotate a sign that the magnetic field rotates clockwise
01:12
this the the joke is replaced with the
01:20
capacitor the
01:32
but
01:35
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
