$$d\phi = EdA$$

However, I am told that since the magnitude electrical field is the same because the distance from the charge is the same at each point, this is true:

$$\phi = EA$$

I don't understand how the magnitude of the electrical field is the same in every point of the sphere. For example,

**wouldn't the magnitude at r= 0.5R be greater than the magnitude at r=R? How can the magnitude be the same?**
