Question

Magnetic flux and magnetic induction differ in the dimensions of:

• A. mass
• B. length
• C. time
• D. all of these

Answer 1

The correct option is B length

Magnetic flux = Magnetic Induction $\times$ Area $=\left[M{L}^2{I}^{-1}{T}^{-2}\right]$
Magnetic Induction field strength $=\left[M{I}^{-1}{T}^{-2}\right]$
Hence, dimensions differ in length.
