Which of the following rule is used to find the direction of magnetic field associated with a current carrying conductor?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Maxwell’s corkscrew rule.
Maxwell's corkscrew rule is another method used to determine the direction of the magnetic field around a current-carrying conductor. According to this rule:
Imagine a right-handed corkscrew placed along the conductor.
If you turn the corkscrew in the direction of conventional current flow (from positive to negative), then the direction in which the corkscrew advances represents the direction of the magnetic field lines around the conductor.
