Q171 / 180 · COMEDK 2013 · Physics

A current flows in a conductor from East to West. The direction of the magnetic field at a point above the conductor is

  • A
    towards East
  • B
    towards West
  • Correct answer
    C
    towards North
  • D
    towards South

Solution

According to right hand rule, the thumb points in the direction of current, i.e. from East to West, then the curled fingers at a point above the conductor will point in the direction of magnetic field, i.e towards North.

Hence, the correct answer is option: 'C'.
