Question

The dimensional formula for magnetic flux is:

• A. \([ML^2T^{-2}A^{-1}]\)
• B. \([MLT^{-2}A^{-1}]\)
• C. \([ML^2T^{-1}A^{-2}]\)
• D. \([ML^2T^{-2}A]\)

Hint:

Magnetic flux = magnetic field × area.

Answer 1

The Correct Option is A

Magnetic flux \(\Phi = BA\). \[ [B]=\frac{F}{IA}=\frac{MLT^{-2}}{AT} \Rightarrow [\Phi]=ML^2T^{-2}A^{-1} \]
