Question

The law which helped you to find the direction of magnetic field lines is:

पर्याय

• Oerested law

• Right hand thumb rule

• Maxwell’s Cork screw Rule

• both Right hand thumb rule and Maxwell’s Cork screw Rule

Answer 1

Both Right hand thumb rule and Maxwell’s Cork screw Rule

Explanation:

The right-hand thumb rule and Maxwell’s cork-screw rule are used to find the direction of magnetic field lines around a current-carrying conductor. In the right-hand thumb rule, the thumb points in the direction of current and the curled fingers give the direction of the field lines. Oersted’s experiment only proves that current produces a magnetic field; it does not give a rule for its direction.
