Final answer:
Magnetic overload relays operate similarly to clamp-on-type ammeters using magnetic force, demonstrated by galvanometers in analog meters.
Explanation:
Magnetic overload relays operate based on the same principle as clamp-on-type ammeters, using magnetic force on a current-carrying loop to open and close electrical contacts. The galvanometer at the heart of analog meters, like ammeters, relies on this principle for accurate readings.
