True or False: Electromagnetic meter movements may be classified as moving coil and moving iron.

Electromagnetic meter movements can indeed be classified as moving coil and moving iron. This classification is based on the design and operation principles of the meters.

Moving coil meters operate on the principle of a coil placed within a magnetic field. When an electric current flows through the coil, it generates a magnetic field that interacts with the external magnetic field, causing the coil to rotate and the needle to move, indicating the measurement.

On the other hand, moving iron meters use a ferromagnetic element that responds to the magnetic field created by the current passing through a coil, causing the iron to move and, consequently, moving the pointer along the scale. This design is particularly useful for measuring both AC and DC currents.

This distinction highlights the fundamental differences in how each type of electromagnetic meter movement operates, making the statement true.
