A galvanometer and a motor both have coils in a magnetic field, but they serve different functions. A galvanometer is used to measure small electric currents, while a motor is used to convert electrical energy into mechanical motion. The main difference is that a galvanometer typically has precise and sensitive measurement capabilities, whereas a motor is designed for generating rotational movement.
A galvanometer measures charge by detecting the flow of electric current through a coil of wire which generates a magnetic field. As charge flows through the coil, it causes a deflection in a needle or pointer on the galvanometer's display, indicating the magnitude of the charge passing through the circuit.
Both a galvanometer and an electric motor operate based on the principle of electromagnetic induction. They both have coils of wire that interact with a magnetic field to generate movement. Additionally, both devices can be used to measure or detect changes in electrical current.
A small current passes through the coil that actuates the pointer. When you select different ranges on the instrument you are in fact selecting different resistors so that the sensitivity of the pointer is changed.
Yes, it is correct to say that an electric motor is a simple extension of the physics that underlies a galvanometer. Both devices operate based on the principles of electromagnetism, where electrical current interacts with magnetic fields to produce motion. The key difference is that a galvanometer is designed to measure small electrical currents, while an electric motor is engineered to convert electrical energy into mechanical motion for performing work.
In an electrical motor, electrical energy is converted into mechanical energy to produce motion. In a galvanometer, electrical energy is converted into mechanical movement of the pointer in response to the flow of current.
Well, darling, a galvanometer is a device used to detect and measure small electric currents, while an electric motor is a device that converts electrical energy into mechanical energy to produce motion. So, in simpler terms, one tells you how much juice is flowing, and the other one actually does the heavy lifting. Hope that clears things up for you, sugar!
That depends if it is an ac or dc motor.
To measure small amounts of current in a circuit, it is utilized with the motor effect.
Moving coil galvanometer? If so, it is effectively an electric motor acting against a spring. the force from the motor is proportional to the current and the force from the spring is proportional to displacement. When they are equal, the needle (attached to the motor), stops. Moving iron meters rely on opposite magnetic poles repelling.

Well, both work on what is termed the 'motor principle', i.e. a current-carrying conductor, when placed in a magnetic field, is subject to a force perpendicular to that field. But that's where the similarity ends, for the operating coil in a galvanometer is restricted to move within an arc, whereas a motor's coil will continuously rotate.

What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
