Question

The unit Wbm\(^2\) is equal to ______.

• A. henry
• B. watt
• C. dyne
• D. tesla

Hint:

Magnetic flux density is measured in tesla, equivalent to Wb/m\(^2\).

Answer 1

The Correct Option is D

The unit of magnetic flux is the weber (Wb). Magnetic flux density \( B \) is flux per unit area: \[ B = \frac{\text{Wb}}{\text{m}^2} \quad \Rightarrow \quad \text{Wb/m}^2 = \text{tesla}. \] Thus, Wbm\(^2\) is a typo for Wb/m\(^2\), which is tesla.
Answer: tesla.
