The unit of magnetic induction is

  1. A \(\mathrm{Wb} \mathrm{m}^{-2}\)
  2. B \(\mathrm{Wb} \mathrm{m}^{-1}\)
  3. C Wb A
  4. D Wb
Verified Solution

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 \(\mathrm{Wbm}^{-2}\).
