The unit of magnetic induction is
- A \(\mathrm{Wb} \mathrm{m}^{-2}\)
- B \(\mathrm{Wb} \mathrm{m}^{-1}\)
- C Wb A
- D Wb
Answer & Solution
Correct Answer
(A) \(\mathrm{Wb} \mathrm{m}^{-2}\)
Step-by-step Solution
Detailed explanation
Magnetic flux passing through a surface is given as \(\phi=B A\) where, \(A=\) area and \(B=\) magnetic induction. \(\therefore \quad B=\frac{\phi}{A} \mathrm{~Wb} / \mathrm{m}^2\) \(\therefore\) Unit of magnetic induction \(B\) is \(\mathrm{Wbm}^{-2}\).
