WebA galvanometer is a type of ammeter. A current when passing through the circuit, makes the magnetic needle to turn at right angles to the circuit for its direction is collateral to the … WebThe galvanometer was augmented by the operation of the needle of a magnetic compass when it is brought to the electric wire. The Danish physicist and chemist first discovered in the year 1820 a small amount of current and a measurable device to create a magnetic field called ‘Hans Christian Ørsted’. WebApr 8, 2024 · The direction of deflection in a galvanometer is reversed if the direction of motion (or polarity of the magnet) is reversed. This indicates that whenever there is a change in the magnetic flux linked with a coil, an emf is induced. The induced emf lasts so long as there is a change in the magnetic flux linked with the coil. オムロン h5s-yfa4-x
