Question
The direction of magnetic lines of force produced by passing a direct current in a conductor is given by:
- Faraday’s law
- Lenz’s law
- Fleming’s left-hand rule
- Right-hand thumb rule
Hint:
The direction of magnetic lines of force produced by passing a direct current in a conductor is given by: fleming's left-hand rule or right-hand thumb rule.
The correct answer is: Right-hand thumb rule
- The right-hand palm rule determines the direction of the magnetic line generated by the direct current to the conductor.
- According to the law of the right hand, the thumb of the right-hand points to V, the fingers to B, and the force (F) is directed perpendicular to the palm of the right hand when a positive conduction charge is present.
