Question

The magnetic field at a point due to a current carrying conductor is directly proportional to:

• A. resistance of the conductor
• B. thickness of the conductor
• C. current flowing through the conductor
• D. distance from the conductor

Hint:

The magnetic field around a current-carrying conductor is proportional to the current flowing through it and inversely proportional to the distance from it.

Answer 1

The Correct Option is C

Step 1: The magnetic field at a point due to a current-carrying conductor is given by Ampere's Law, which states that the magnetic field is directly proportional to the current \( I \) flowing through the conductor.
Step 2: Therefore, the correct option is the current flowing through the conductor, as it is the factor that affects the magnetic field produced around the conductor.

Final Answer: \[ \boxed{\text{current flowing through the conductor}} \]
