Ques: What is the dimensional formula of magnetic flux/electric flux?

Ans: In physics, the dimensional formula of magnetic flux is given by:

Magnetic Flux = [M] [L]2 [T]-2 [I]-1

Where:

also, the dimensional formula of electric flux is given by:

[Electric Flux] = [M] [L]3 [T]-3 [I]-1

Therefore, the dimensional formula of magnetic flux to electric flux can be obtained by dividing the dimensional formula of magnetic flux by the dimensional formula of electric flux. 

Thus, the dimensional formula of Magnetic flux/Electric flux = [M] [L]2 [T]-2 [I]-1/[M] [L]3 [T]-3 [I]-1 = [L]-1 [T]

Important Facts about Electric Flux & Magnetic Flux

  • Magnetic flux is a physical quantity which can be defined as a measure of the strength of a magnetic field passing through a given area. It is used to describe the behaviour of magnetic fields in different materials.
  • Electric flux is a measure of the strength of an electric field passing through a given area. It is calculated by taking the dot product of the electric field vector and the area vector.
  • The ratio of magnetic flux to electric flux is measured in inverse length and time.
  • The ratio of electric flux to magnetic flux is given by Electric flux/magnetic flux = [M] [L]3 [T]-3 [I]-1/[M] [L]2 [T]-2 [I]-1
  • Dimensional of electric flux to magnetic flux is LT−1
