Explain the working principle of a Moving Iron (MI) instrument. How does it differ from a Moving Coil (MC) instrument in terms of construction, operation, and applications?

Explain the working principle of a Moving Iron (MI) instrument. How does it differ from a Moving Coil (MC) instrument in terms of construction, operation, and applications?
Answer : **Working Principle of Moving Iron (MI) Instrument:** A Moving Iron (MI) instrument works on the principle of electromagnetic attraction. When current flows through a coil, it creates a magnetic field. This ... galvanometers and ammeters. Let me know if you'd like me to add or tweak anything!...
