A commonly used sensor that induces an AC voltage by having a rotating reluctor cut through a permanent magnetic field is used for:

A) wheel speed sensors
B) transmission tailshaft speed sensors
C) engine speed sensors
D) all of the above

AC Voltage

AC voltage stands for alternating current voltage, where the flow of electric charge periodically reverses direction, commonly used in homes and industries for powering electrical appliances.

Reluctor

A term used to describe a number of devices that use magnetism and motion to produce voltage.
