The value of _ around a current carrying wire is found by Ampere's circuital law.
Correct answer: D. All of these
- A. Magnetic field strength
- B. Magnetic flux density
- C. Magnetic induction
- D. All of these
Explanation
Ampere's circuital law relates the line integral of the magnetic field around a closed loop to the total current passing through that loop. This law is used to calculate the magnetic field B, which is also known as magnetic flux density or magnetic induction.

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.
