Q:

What is a moving coil galvanometer?

A:

Quick Answer

According to Dictionary.com, a moving coil galvanometer is a galvanometer that is operated by an electric current flowing in a movable coil that is suspended in a magnetic field. A galvanometer is an instrument used to detect the existence of small electric currents and determine their strength.

Full Answer

The galvanometer was once referred to as the moving coil electric current detector. If an electric current is present, it passes through the coil of the galvanometer and the coil experiences a torque proportionate to this current. This mechanism is most accurate when the magnetic field that suspends the coil is uniform and constant.

  • Q:

    How does a dynamo work?

    A:

    Dynamos produce electric current by rotating a wire within a magnetic field. Another method rotates a permanent magnet around coils of wire. Both processes produce alternating current because the wire passes between two magnetic poles every half turn. A commutator can turn the alternating current into direct current pulses, a common practice in early days before alternating current became the standard.

  • Q:

    What is the function of a galvanometer?

    A:

    A galvanometer uses movements of a coil within a magnetic field or a magnetic needle to measure or detect a small electric current. The galvanometer was the first instrument that scientists used to pick up and quantify electrical currents, and these devices were the first to locate electrical activity in the brain and heart.

    How does a windmill produce electricity?

    A:

    Windmills produce electricity by electromagnetic induction, the process in which the movement of magnets in a magnetic field generates electricity. In a windmill, when wind moves the blades of the windmill that move the rotor, the rotor rotates a shaft that holds magnets in the magnetic field of the generator, generating alternating current that is sent along power lines.

  • Q:

    How does a dynamo generator work?

    A:

    A dynamo generates electricity by using a magnetic field to imbue wires with an electric current. According to the Edison Tech Center, this process generates a direct current that can then be fed down the wires to an alternator for conversion to an alternating current; these alternators are sometimes known as generators.
