In summary, a square loop with resistance 15 ohms and side length 8.2 cm is placed perpendicular to a time varying magnetic field with a rate of change of 3.4 x 10^-7 T/s. The diagram should include the loop, magnetic field, and current. The rate of change of magnetic flux threading the loop can be calculated using the equation I = Bvl/R. Additionally, Faraday's Law can be used to calculate the current circulating the loop. A good resource for finding information on electric flux is a textbook or online database.

## The Attempt at a Solution

wheres a good site to look up electric flux

Are you working from a book? You need the equation for flux (hint: it's related to magnetic field and enclosed area), and Faraday's Law.

?

A good site to look up electric flux would be any reputable physics textbook or online educational resource, such as Khan Academy or Physics Classroom. These resources will provide clear explanations and examples of electric flux, as well as relevant equations and practice problems. Additionally, websites such as HyperPhysics or Physics Forums may also be useful for further understanding and discussion of electric flux.

## 1. What is electric flux?

Electric flux is a measure of the electric field passing through a given area. It is a scalar quantity, meaning it has magnitude but no direction.

## 2. How is electric flux calculated?

Electric flux is calculated by taking the dot product of the electric field and the area vector of a given surface. The formula is ΦE = E * A * cosθ, where E is the electric field, A is the area vector, and θ is the angle between them.

## 3. Where can I find a good site to look up electric flux?

There are many reputable websites that provide information on electric flux, such as Khan Academy, Physics Classroom, and HyperPhysics. It is also recommended to consult textbooks or scholarly articles for more in-depth information.

## 4. What is the unit of measurement for electric flux?

The unit of measurement for electric flux is volt meters squared (V m2), also known as the SI unit of electric field. In some cases, it may also be expressed as newton meters squared per coulomb (N m2/C).

## 5. How is electric flux related to Gauss's Law?

Gauss's Law states that the electric flux through a closed surface is equal to the charge enclosed by that surface divided by the permittivity of free space. In other words, the amount of electric flux passing through a surface is directly proportional to the amount of charge enclosed by that surface.
