Question

The direction of a magnetic field due to a straight current carrying conductor can be determined using?

• A. Fleming's left-hand rule
• B. right hand thumb rule
• C. Fleming's right-hand rule
• D. left hand thumb rule

Answer 1

Answer:

B. right hand thumb rule

• The direction of a magnetic field around a straight, current-carrying conductor can be determined using the right-hand rule (also known as the right-hand thumb rule).

• Maxwell's right-hand thumb rule can be used to determine the direction of the magnetic field lines around a straight current-carrying conductor.

• It states that, if the thumb of the right hand represents the direction of current flow, the rest of the bent fingers determine the direction of the magnetic field around it.
