Question

One needs the help of which of the following rules to know the direction of the magnetic field produced due to a current carrying conductor?

• A. Fleming's right hand rule
• B. Fleming's left hand rule
• C. Right hand thumb rule
• D. Ohm's law

Hint:

To find the direction of the magnetic field around a current carrying conductor, use the Right Hand Thumb Rule.

Answer 1

The Correct Option is C

Step 1: Understanding the concept.
To determine the direction of the magnetic field produced by a current carrying conductor, we use the Right Hand Thumb Rule.
Step 2: Right Hand Thumb Rule.
According to the Right Hand Thumb Rule, if you hold the conductor with your right hand such that the thumb points in the direction of the current, then the curl of your fingers will show the direction of the magnetic field around the conductor.
Step 3: Conclusion.
Thus, the correct answer is (C) Right hand thumb rule.
