Question

The direction of current in a conductor can be obtained by:

Options

• Fleming’s right hand rule

• Fleming’s left hand rule

• Right hand thumb rule

• Maxwell’s cork-screw rule

Answer 1

Right hand thumb rule

Explanation:

The right hand thumb rule states that if the thumb of the right hand points along the direction of current, the curled fingers give the direction of the magnetic field around the conductor. So the direction of current in a straight conductor can be obtained by this rule. Fleming’s right hand rule gives the direction of induced current in a moving conductor, and Fleming’s left hand rule gives the direction of force on a current-carrying conductor.
