What is the device that turns a needle in a galvanometer?
The device that turns a needle in a galvanometer is called a coil. The coil generates a magnetic field when current flows through it, which interacts with the magnetic field produced by the permanent magnet in the galvanometer to cause the needle to deflect.
True or false The device that turns a needle in a galvanometer is called an electromagnet.?
True. An electromagnet is used in a galvanometer to create a magnetic field that interacts with the current-carrying coil and causes the needle to move.
Does galvanometer have polarity?
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
Why needle of tangent galvanometer move by increasing and decreasing current?
The galvanometer is oriented so that the plane of the coil is vertical and aligned along parallel to the horizontal component He of the Earth's magnetic field (i.e. parallel to the local "magnetic meridian"). When an electrical current flow through the galvanometer coil, a second magnetic field H is created. At the center of the coil, where the compass needle is located, the coil's field is perpendicular to the plane of the coil. These two perpendicular magnetic fields add vertically, and the compass needle points along the direction of their resultant He + H. The current in the coil causes the compass needle to rotate by an angle\ \theta.
The device that turns a needle in a galvanometer is called an electromagnet?
The device that turns a needle in a galvanometer is called a coil or a solenoid. It generates a magnetic field when current passes through it, causing the needle to deflect in response to the current being measured.

Why tangent galvanometer is called tangent galvanometer?
A tangent galvanometer is called so because it uses the tangent of the angle through which a magnetic needle is deflected to measure electric current. The horizontal component of the Earth’s magnetic field and a coil carrying current creates a magnetic field that deflects the needle, making it tangent to the circle of the coil.
How could you protect the galvanometer against large scale out of balance conditions?
You can protect the galvanometer against large-scale out-of-balance conditions by installing overload protection devices like fuses or current limiters in the circuit. You can also use damping techniques to prevent the galvanometer needle from swinging too wildly when an imbalance occurs. Regular maintenance and calibration checks can help identify and address any potential issues before they cause damage to the galvanometer.
How galvanometer measures the charge?
A galvanometer measures charge by detecting the flow of electric current through a coil of wire which generates a magnetic field. As charge flows through the coil, it causes a deflection in a needle or pointer on the galvanometer's display, indicating the magnitude of the charge passing through the circuit.
Does a galvanometer transform electrical energy into mechanical energy?
A galvanometer is an instrument that is used to measure current or voltage. It can have a mechanical movement, ie a needle that moves round a scale, or it can be digital as many are now.
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 is the basis of the function of a galvanometer?
The function of a galvanometer is based on the interaction between a magnetic field and an electric current passing through a coil of wire. When a current flows through the coil, it creates a magnetic field that interacts with a permanent magnet, causing a deflection of the needle on the galvanometer scale.
How do you make a galvanometer?
To make a simple galvanometer, you will need a small compass needle, a coil of wire, a magnet, and a base to mount the components. Wind the coil of wire around the compass needle and connect the ends of the wire to a power source. When a current flows through the coil, it will interact with the magnetic field created by the magnet, causing the needle to deflect, indicating the presence and direction of the current.
