COMEDK · Physics · 21. Magnetic Effects of Current
A current flows in a conductor from East to West. The direction of the magnetic field at a point above the conductor is
- A towards North
- B towards South
- C towards East
- D towards West
Answer & Solution
Correct Answer
(A) towards North
Step-by-step Solution
Detailed explanation
The direction of magnetic field in a current carrying straight wire is given by right hand thumb rule. If we point our thumb in a direction of East to West, the direction of magnetic field is found to be towards North, which is given by the curled fingers of our hand.
