Web17 dec. 2024 · Moving coil-Galvanometer: Moving Magnet Galvanometer (i) In it powerful magnet is used. Due to this there is no effect of external magnetic filed on it. (i) Its controlling region is earth's region whose value is very small. So, there is a big effect of external magnetic field on it. Due to this accurate defletion value is not found. WebThe induced emf in a coil is equal to the rate of change of flux linkage. The flux linkage is the product of the number of turns in the coil and the flux associated with the coil. The formula of Faraday’s law is given below: ε = − N Δ ϕ Δ t. Where ε is the electromotive force, Φ is the magnetic flux, and N is the number of turns.
