What are MI type instruments?
Understand the Problem
The question is asking about MI type instruments, which refers to measuring instruments that use magnetic induction. The inquiry seems to be about what these instruments are, how they work, and their applications.
Answer
Moving Iron (MI) instruments measure AC/DC currents and voltages using magnetic attraction or repulsion.
Moving Iron (MI) instruments are used to measure alternating and direct currents and voltages. They operate on the principle of magnetic attraction or repulsion acting on a piece of soft iron within a magnetic field.

More Information
Moving iron instruments are typically more robust and cheaper than other types, such as moving coil instruments, making them popular for a range of applications where precision is less critical.
Tips
A common mistake is assuming that these instruments are only for AC measurements, but they can measure both AC and DC.
