$The dimensional formula of magnetic flux is$

Topic: NEET PYQ

Answer: C. Full step-by-step solution below.

A $[M^{0} L^{- 2} T^{- 2} A^{- 2}]$
B $[M L^{0} T^{- 2} A^{- 2}]$
C $[M L^{2} T^{- 2} A^{- 1}]$
D $[M L^{2} T^{- 1} A^{3}]$

Correct answer: C

Solution

(c) Magnetic flux, ϕ = BA = (\frac{F}{ll}) A = \frac{[ ML T ^{- 2} ] [ L ^{2} ]}{[ A ] [ L ]} = [M L^{2} T^{- 2} A^{- 1}] .
