Rotating magnetic field - Wikipedia
The rotating magnetic filed is the key principle in the operation of induction machines. The induction motor consists of a stator and rotor. In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current. The rotor or armature consists of coils wound in slots, which are short circuited and in which the changing fluxgenerated by the field poles induce a current. The flux generate…AC Magnetic Field Generator - accelinstruments,To generate alternating magnetic field, a waveform amplifier is needed to drive the resonant circuit as shown in Figure 2. The function generator produces a sinewave. The sinewave is amplifier by a driver amplifier such as the TS200 or the TS250. It can amplify the function generator voltage or current or both. The waveform amplifier is driving a large current into the current-Alternating current and magnetic fields | Physics Forums,09.04.2013· There is a magnetic B field whenever there is a current in any form, line current, surface current or volume current.

If you have an alternating current running through a wire, of course there will be a magnetic field, and possibly also an electric field.Induction heating - Wikipedia,The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents. The eddy currents flowing through the resistance of the material heat it by Joule heating. In ferromagnetic (and ferrimagnetic) materials like iron, heat may also be generated by magnetic hysteresis losses.The Study of Alternating Magnetic Fields | Physics or,,28.03.2020· An alternating magnetic field repels a non-ferrous conductor because non-ferrous conductors have a certain atomic structure which allows easy movement for the electrons. When the alternating magnetic field makes the electrons within the conductor move in different directions rapidly, the movement of electrons creates an electromagnetic field around the conductor. My observations5.4.3 The alternating magnetic field,field and an alternating magnetic field, an approach which is at least permissible in the linear medium air. While the magnet is a nonlinear system, the relative flux changes are sufficiently small (1%) to support a linearization with good approximation. Still, the above superposition must not be misunderstood in the sense that the paths in space of the static and the alternating flux would,
