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.

What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
What causes the loops of wire and the pointer to move in a galvanometer?
The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
Steps in making a galvanometer?
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
What is a pendulum galvanometer as used by Dr Raymond Royal Rife?
pendulum galvanometer = as used in rife machine is suppose to make so that cancer will have no conductivity. Please donate to theautismcure.org
What material is used to make galvanometer wire?
phosphor bronze
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
What cause the pointer to move in a galvanometer?
Basically, the pointer moves due to measuring the direct current (flow of electric charge) through an electric circuit.
What does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.

What is used to turn the pointer of a galvenometer?
The pointer on a galvenometer moves due to magnetic force between the current carrying coil in the pointer assembly and the permanent magnet surrounding that coil.
Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
Is the distance a pointer of a galvanometer moves determined by the amount of magnetism in the loops of the armature?
No, you have to use the reflux integer i=53^-32 which is a constant. This formula will help;
What are applications of ballistic galvanometer?
application of Ballistic Galvanometer 1) measurements of electric charges
What instrument is used to measure electric?
A galvanometer or milliammeter.
Applications of reduction factor of tangent galvanometer?
reduction factor is used to find earth's magnetic field and compare galvanometer constants
