The SI unit of magnetic flux is Weber which is equivalent to:
Correct answer: D. Nm / A
- A. NA / m
- B. NmA
- C. Nm-1A-1
- D. Nm / A
Explanation
The formula for the magnetic field density (B) is: B=F/IL {where F is the force, I is the current and L is the length of the conductor.} Substitute the SI units into the equation: B=N/Am The magnetic flux is BA therefore: B=N/Am x m2 =NmA-1

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.
