SI unit of flux density is____________________?
Correct answer: A. NA-1m-1
- A. NA-1m-1
- B. NAm-1
- C. NmA-1
- D. NmA-2
Explanation
Magnetic flux density has the SI unit tesla, and 1 T = 1 N A^-1 m^-1. Students may choose d, N m A^-2, because it is dimensionally equivalent to a tesla in some rearrangements, but the standard SI form given here is N A^-1 m^-1.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
