GEOLOGY

Detailed explanation-1: -A galvanometer works by deflecting a pointer in response to an electric current flowing through a coil in a constant magnetic field. Galvanometers can be thought of as a kind of actuator.

Detailed explanation-2: -The induced current can be measured by an ammeter or oscilloscope. If you move the bar magnetic’s axis parallel to the axis of the solenoid, you will get the maximum magnetic flux. This will result in the maximum emf or the maximum current flowing through the wire.

Detailed explanation-3: -galvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.

Detailed explanation-4: -Explanation of Correct Option: Flux meter is a device which is used to measure the magnetic flux of a permanent magnet. And magnetic flux can be defined as the number of magnetic field lines crossing a given closed surface.

Detailed explanation-5: -The galvanometer is used to measure the voltage by connecting it in series with high resistance.
