Question

Identify the correct dimensions of magnetic flux.

(a) [M^3 L^2 A^-1 T^-2]

(b) [M L^2 A^-1 T^-2]

(c) [M^2 L^2 A^-1 T^-2]

(d) [M L^2 A^-1 T^2]

The question was asked in an online quiz.

The question is from Electromagnetic Induction topic in portion Electromagnetic Induction of Physics – Class 12

Answer 1

Right choice is (b) [M L^2 A^-1 T^-2]

The best I can explain: Magnetic flux = Magnetic field × Area.

Flux = \(\frac { ( [ M L T^{-2} ].[ L^2 ])}{(A L) }\)

Flux = \(\frac { [M L^2 T^{-2} ] }{ [ A ] }\)

Flux = [M L^2 A^-1 T^-2].
