A steady current passing through a conductor produces:
Correct answer: B. Magnetic field
- A. Electric field
- B. Magnetic field
- C. Both of these options are correct
- D. None of these options are correct
Explanation
Oersted's Law states that when a steady electric current is passed through a metallic conductor, it creates a magnetic field around it.

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.
