FAQs

How do you calculate electric flux? Electric flux (Φ) is calculated by multiplying the electric field (E) perpendicular to the surface and the area (A) of the surface: Φ = E * A * cos(θ), where θ is the angle between the electric field and the normal to the surface.

How do you calculate flux using Gauss law? Gauss’s law states that the electric flux through a closed surface is equal to the total enclosed charge divided by the permittivity of free space (ε₀): Φ = Q / ε₀.

What is the formula for magnetic electric flux? There is no specific formula for “magnetic electric flux” as it’s a combination of two different concepts. Magnetic flux (Φ) can be calculated using a similar formula as electric flux, but it involves the magnetic field (B) and the area (A) instead: Φ = B * A * cos(θ).

Is electric flux a scalar or vector? Electric flux is a scalar quantity, meaning it has magnitude but no direction. It represents the total flow of electric field lines through a surface.

Why do two electric field lines never intersect each other? Electric field lines never intersect because they represent the direction of the electric force experienced by a positive test charge. If they were to intersect, it would imply multiple directions of force at a single point, which is not physically meaningful.

Is electric flux always perpendicular? Electric flux is generally calculated perpendicular to the surface because it’s a measure of the number of field lines passing through the surface. However, in cases where the electric field is not perpendicular to the surface, the flux is adjusted by using the cosine of the angle between the field and the normal.

Does electric flux change? Electric flux can change if the electric field strength or the area changes. It is affected by variations in the electric field or the orientation of the surface relative to the field.

Why is R Squared in Coulomb’s law? Coulomb’s law has an inverse-square relationship due to the geometry of three-dimensional space. The electric field spreads out uniformly in all directions, leading to the 1/r² relationship.

What is Coulomb’s first law? Coulomb’s first law, also known as the law of electrostatics, states that like charges repel each other, while opposite charges attract each other with a force directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Why Coulomb’s law is not valid for moving charges? Coulomb’s law is valid for stationary charges, but it becomes inaccurate for moving charges due to relativistic effects and the creation of magnetic fields associated with moving charges.
