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.

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.
The strength of electric and magnetic fields remains constant as you move away from the source of the electric and magnetic fields?
yes
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.
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.
What is turned in a galvanometer?
A galvanometer measures small electric currents and it typically consists of a coil of wire suspended in a magnetic field. When current flows through the coil, it generates a magnetic field that interacts with the external magnetic field, causing the coil to rotate, which is then indicated on a scale to show the current strength.
Do magnetic field lines close together indicate a weaker magnetic field?
No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.
