Question

A coil of wire that is carrying a current and produces a magnetic field is

A. a galvanometer.
B. a solenoid.
C. a magnetic domain.
D. an electric motor.

Answer 1

The correct option here is a Solenoid

Step-by-step explanation:

A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.

Answer 2

A coil of wire that is carrying a current and produces a magnetic field is called a solenoid. So the correct option is option "B", in regards to the question given. The term solenoid was first invented by the famous French physicist named Andre-Marie Ampere. In the terms of a physicist, it indicates a coil that has a far greater lenth than the diameter and is wrapped around a core made of metal to create a uniform magnetic field. If a compass is brought near the wire through which current is passing, it will indicate the direction in which the current is flowing.
