The SI unit of magnetic flux density is the
Correct answer: B. tesla
- A. weber
- B. tesla
- C. henry
- D. gauss
Explanation
One tesla is one weber per square metre, so the tesla measures flux density while the weber measures the total flux. The tesla is a large unit: the Earth's field is only about 50 microtesla, while an MRI scanner reaches 1.5 T or more. The henry is the unit of inductance and the gauss is the old CGS unit, with 1 T equal to 10,000 gauss.

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.
