How does a galvanometer use a magnetic field to indicate the strength of an electric current?
A galvanometer consists of a coil of wire suspended in a magnetic field. When an electric current passes through the coil, it generates a magnetic field that interacts with the external magnetic field, causing the coil to move. The amount of deflection is proportional to the current strength, allowing the galvanometer to indicate the current passing through it.

What is weston galvanometer?
A weston galvanometer is a type of sensitive instrument used to detect and measure small electric currents. It uses a moving coil suspended in a magnetic field to deflect in response to the current passing through it. This deflection is then used to indicate the strength of the current.
What is the principle of galvanometer?
Galvometer works on the principle of conversion of electrical energy into mechanical energy. It is an instrument used to indicate the presence, direction or strength of a small electric current.
What is a moving iron galvanometer?
A moving iron galvanometer is a type of electrical measuring instrument that uses a coil of wire and a movable iron needle to detect and measure electric currents. When current flows through the coil, it creates a magnetic field that moves the iron needle, which indicates the strength and direction of the current.
Which circumstances would a current register on the galvanometer?
A current would register on a galvanometer when there is a flow of electric charge through the circuit that the galvanometer is connected to. The galvanometer measures the strength and direction of the current passing through it, displaying this information as a deflection on its dial.
What The distance that the pointer of a galvanometer moves depends on the amount of magnetism in the loops of the armature?
The distance that the pointer of a galvanometer moves is determined by the strength of the magnetic field present in the coils or loops of the armature. When an electric current flows through the coils, it interacts with the magnetic field produced by the coils, resulting in a deflection of the pointer. The greater the magnetism in the loops, the larger the deflection of the pointer.

Why is it called as reduction factor in tangent galvanometer?
The term "reduction factor" in a tangent galvanometer refers to the ratio of the magnetic field strength produced by the coil of the galvanometer to the Earth's magnetic field strength. It quantifies how much the deflection of the galvanometer's needle is reduced due to the presence of the magnetic field generated by the coil compared to the Earth's magnetic field. This factor is essential for accurately measuring current in the circuit by relating the tangent of the angle of deflection to the current flowing through the coil.

What is the difference between electrodynamometer and galvanometer?
Electrodynamometer: An instrument that measures large amount of electric current by indicating the strength of repulsion or attraction between the magnetic fields of two sets of coils, one fixed and one movable. whereas, Galvanometer: An instrument for detecting and measuring small electric currents.
What is the difference between a galvanometer and an ammeter?
A galvanometer is a device used to detect small electric currents, while an ammeter is a device used to measure the strength of electric currents. The main difference is that a galvanometer is more sensitive and used for detecting small currents, while an ammeter is used for measuring larger currents.
The strength of electric and magnetic fields remains constant as you move away from the source of the electric and magnetic fields?
yes
What does a galvonometer measure?
A galvanometer measures electric current by detecting the presence and strength of the current flowing through it. It typically consists of a coil of wire within a magnetic field, which causes the coil to deflect in proportion to the current passing through it.
What measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
A galvanometer measures current by deflecting a coil of wire in a magnetic field. The current flowing through the coil generates a magnetic field that interacts with the permanent magnetic field, causing the coil to deflect. The amount of deflection is proportional to the current strength flowing through the coil.
How ammeter is made?
An ammeter is typically made using a sensitive galvanometer, which consists of a coil of wire suspended in a magnetic field. When electric current passes through the coil, it generates a magnetic force that causes the coil to rotate, moving a needle across a calibrated scale to indicate the current's strength. To measure larger currents, shunt resistors are often used in parallel with the galvanometer, allowing it to measure higher currents without damaging the sensitive components. The construction may also include protective casing and terminals for easy connection in a circuit.
