Singlephase stator produces a nonrotating, pulsating magnetic field. Another view is that the singlecoil excited by a singlephase current produces two counterrotating magnetic field phasors, coinciding twice per revolution at 0° (Figure abovea) and 180° (figure e). When the phasors rotate to 90° and 90° they cancel in figure c.

Testing of Circuit Breaker Testing of circuit breakers is more difficult as compared to other electrical equipment like transformer or machine because the short circuit current is very large. Testing of the transformer is mainly divided into two groups, type tests, and routine tests.

An electric field has a clearly defined physical meaning: simply the force exerted on a 'test charge' divided by the amount of charge. Magnetic field strength cannot be measured in the same way because there is no 'magnetic monopole' equivalent to a test charge. Do not confuse magnetic field strength with flux density, B. This is closely related to field strength but depends also on the material within the field.

The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change. As with magnetizing a magnet, demagnetizing a magnet is also possible.

The rotor contains magnetic poles with windings wrapped around them to form coils. These coils are called field coils or field windings because they create a magnetic field when excited with a DC current. Typically, the generator field windings contain many turns. A magnetic field radiates out from the rotor as lines of magnetic flux.
