Question

State the rule to determine the direction of the magnetic field produced around a straight conductor carrying current.

Answer 1

Solution:

1. Magnetic Field produced around a straight current-carrying conductor:
2. Maxwell's Right-Hand Thumb Rule can be used to determine the direction of magnetic field lines around a current-carrying conductor.
3. It states that, if the thumb of the right hand represents the direction of the current flow, the rest of the curled fingers determine the direction of the magnetic field around it.
4. The figure below represents the same.

This is the rule that can determine the direction of the magnetic field produced around a straight conductor carrying current.
