The rectangular coil of a galvanometer is made of:
Correct answer: C. Enamelled copper wire
- A. Enamelled steel wire
- B. Copper wire
- C. Enamelled copper wire
- D. None of these
Explanation
Enamelled copper wire is a type of copper wire that is coated with a thin layer of insulation, typically made of enamel. This insulation helps to prevent short circuits and ensures that the coil does not come into direct contact with other conductive materials. Enamelled copper wire combines the conductivity of copper with the insulation properties of enamel, making it well-suited for use in galvanometers and other electrical devices.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
