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 East
- B towards West
- C towards North
- D towards South
Answer & Solution
Correct Answer
(C) towards North
Step-by-step Solution
Detailed explanation
According to right hand rule, the thumb points in the direction of current, i.e. from East to West, then the curled fingers at a point above the conductor will point in the direction of magnetic field, i.e towards North.

When \(L\) is removed from the circuit, the phase difference between the voltage and the current in the circuit is \(\pi / 3\). If instead \(C\) is removed from the circuit, the phase difference is again \(\pi / 3\). The power factor of the circuit isCOMEDK 2023 Medium
