The is a type of electromagnetic device that has a movable iron core called a plunger. [Hint]
differ from solenoids in that the electromagnetic action is used to open or close electrical contacts rather than to provide mechanical movement. [Hint]
A typical speaker is constructed with a permanent magnet and an . [Hint]
The meter movement is the most common type used in analog multimeters. [Hint]
In an analog multimeter, the pointer is deflected in proportion to the amount of through a coil. [Hint]
is a characteristic of a magnetic material whereby a change in magnetization lags the application of a magnetizing force. [Hint]
The ability of a material to maintain a magnetized state without the pressure of a magnetizing force is called . [Hint]
When a conductor is moved through a magnetic field, a is produced across the conductor. [Hint]
law states that the voltage induced across a coil of wire equals the number of turns in the coil times the rate of change of the magnetic flux. [Hint]
law defines the polarity or direction of an induced voltage. [Hint]
