Question

question 7 (0.7 points) technician a says that the magnetic field is created by the stator assembly. technician b says that magnetic field is induced into the rotor assembly. who is correct? 1) technician a only 2) technician b only 3) both technician a and b 4) neither a nor b

Explanation:

In an alternator, the stator has windings where the output current is induced. The rotor (field coil) creates the magnetic field. When the rotor rotates (due to engine power via a belt), its magnetic field cuts across the stator windings, inducing a current in the stator. So Technician A is wrong (stator doesn't create the magnetic field, rotor's field coil does) and Technician B is wrong (magnetic field is from rotor's field coil, not induced into rotor. Rotor's field coil gets current to create magnetic field).

Answer:

1. Neither A nor B
