In the region surrounding a current carrying wire:
Correct answer: A. A magnetic field is setup
- A. A magnetic field is setup
- B. The lines of force are elliptical
- C. Both (a) and (b)
- D. None of these
Explanation
This is correct. According to Ampère's circuital law and Oersted's experiment, a magnetic field is established around a current-carrying conductor.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
