- The Current-Carrying Conductor produces a magnetic Field Around it.
- Biot Savarts Law: The direction and Magnitude of this magnetic field can be obtained from Biot Savarts Law.
Where dB = Magnetic Field produced due to small wire of length dl, I = Current in wire, μ0 = Permittivity of free space, dl = Small Current Element
- The magnetic field generated due to the current-carrying circular conductor at its center is given as:
- This result has been obtained from Biot Savarts Law.
EXPLANATION:
- The Magnetic Field Produced due to the Semi-Circular wire is half of that of Circular wire.
- So, the magnetic field produced at the center of the wire
- Hence option 2 is the correct option.
