Copper is used in moving coil galvanometers because it is a good conductor of electricity, which allows for minimal resistance and efficient flow of currents. Additionally, copper is flexible and ductile, making it ideal for winding into a coil to create the moving part of the galvanometer.

What are the types of galvanometer?
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
What is Construction of moving coil ballistic galvanometer?
A moving coil ballistic galvanometer is a sensitive instrument used to measure small amounts of electric charge. It consists of a coil of wire suspended between two pole pieces of a permanent magnet. When a current passes through the coil, it experiences a torque and deflects, allowing the measurement of charge.
Steps in making a galvanometer?
Wind a coil of wire around a bobbin to create the coil, which will serve as the moving element of the galvanometer. Attach a pointer or index needle to the coil to indicate the deflection caused by the current passing through the coil. Place the coil and pointer assembly within a magnetic field produced by a permanent magnet to allow for the deflection of the pointer in response to current flow. Connect the coil to a calibrated scale to measure the amount of current based on the deflection of the pointer.
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.
Write a brief note on moving coil galvonameter?
A moving coil galvanometer is a device used to measure small electric currents. It consists of a coil of wire suspended in a magnetic field, which causes the coil to move when a current is passed through it. The movement of the coil is proportional to the strength of the current, allowing the device to provide a measurement of the current passing through it.

Write the construction of a moving coil galvanometer?
A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.

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.
Moving a magnet in and out of a coil of wire produces an?
electric current in the coil of wire.
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 a galvanometer works?
Electricity passing through a wire coil creates a magnetic field which twists a suspended magnet and mirror. A light beam reflects off the mirror and onto a scale.
