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.
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.
What can cause a galvanometer needle to move?
A galvanometer needle can be moved by the flow of electric current through its coil, the presence of a magnetic field, or mechanical disturbances like vibrations or shocks.
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.

What is tangent galvanometer?
T.G is a device used for determination of the horizontal component of the magnetic field of the earth,and the internal resistance of T.G T.G consists of : 1-coil of wire of many turns(2 to 500) 2-small magnetic needle at the center of the coil 3-box of resistants
What is galvalometer?
i think this is galvanometer so galvanometer is a device which detect the current as well as it measure small amount of current

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.
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.
Who invented galvanometer?
The galvanometer was invented by Johann Schweigger in 1820. It is a device used to detect and measure electric current.
What is the use of spirit level in the tangent galvanometer?
A spirit level in a tangent galvanometer is used to ensure that the device is perfectly horizontal. This alignment is crucial for accurate measurements of the magnetic field and current, as any tilt can introduce errors in the readings. By leveling the galvanometer, the magnetic needle can respond correctly to the magnetic field produced by the current flowing through the coil. A proper setup ensures reliable and consistent results during experiments.
What effect does the rotating part of the loop have on the needle of the galvanometer?
The rotating part of the loop in a galvanometer generates a changing magnetic field, which induces an electromotive force (EMF) in the coil according to Faraday's law of electromagnetic induction. This induced EMF causes a current to flow through the galvanometer circuit, resulting in the deflection of the needle. The degree of deflection is proportional to the strength of the current, allowing the galvanometer to measure the current's magnitude. Thus, the rotating loop effectively converts mechanical motion into an electrical signal detectable by 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.
