Question & Answer

The SI unit of magnetic field is:
A. Tesla
B. Weber
C. Weber-meter
D. Gauss

ANSWER Verified Verified
Hint: In this problem we need to use the SI unit for flux per unit area, since it is equal to the magnetic field. Doing this will solve your problem.

Complete step-by-step answer:

The unit of magnetic field is Tesla. It is the SI unit of magnetic field. Magnetic field is the measure of magnetic flux per unit area.

${\text{1}}\,{\text{tesla = 1}}\,\dfrac{{{\text{weber}}}}{{{{\text{m}}^{\text{2}}}}}$.

Hence, Tesla is the unit of Magnetic field.

So, the correct option is A.

Note: The SI unit of magnetic field is in the name of Nikola Tesla (Symbolized as T). We should know that ${\text{1}}\,{\text{tesla = 1}}\,\dfrac{{{\text{weber}}}}{{{{\text{m}}^{\text{2}}}}}$. We can do this by learning the formula that the magnetic field is equal to flux per unit area also called magnetic density. Knowing this you will get the correct answer.
