Magnetic Effects Of Current Question 92

Question: The dimension of the magnetic field intensity B is [MP PET 2001]

Options:

A) $ ML{{T}^{-2}}{{A}^{-1}} $

B) $ M{{T}^{-2}}{{A}^{-1}} $

C) $ ML^{2}T{{A}^{-2}} $

D) $ M^{2}L{{T}^{-2}}{{A}^{-1}} $

Show Answer

Answer:

Correct Answer: B

Solution:

$ F=Bil $

Þ $ [B]=\frac{[F]}{[i][l]}=\frac{ML{{T}^{-2}}}{AL}=M{{T}^{-2}}{{A}^{-1}} $
