MCQ
What is the space around a current-carrying conductor, in which its magnetic effect can be experienced called?
  • A
    Electric field
  • B
    Magnetic pole
  • C
    Magnetic field
  • D
    Charge distribution

Answer

  1. Magnetic field

Explanation:

The space around a current-carrying conductor, in which its magnetic effect can be experienced is called the magnetic field.

When a current is passed through a conductor, it modifies the space around the conductor and forms a magnetic field.
