In physics, electric flux is a measure of the quantity of electric charge passing through a surface. It is used in the study of electromagnetic radiation. The SI unit of electric flux is the weber (symbol: Wb). The electric flux through a surface is calculated by dividing the electric charge passing through the surface by the area of the surface, and multiplying by the permittivity of free space (the permittivity of vacuum is used in the case of a vacuum). The electric flux through a closed surface is zero, by Gauss's law.

A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field. The term is used for two distinct but closely related fields denoted by the symbols B and H. The term "magnetic field" is often used to refer to the B field. In a vacuum, B and H are the same, whereas in a material medium, B is a component of H. In the latter case, H is the "magnetic field strength", and B is the "magnetic flux".

for the given problem, we consider it closely wounded. A coil which is the radius is equal to six centimeter, six centimeter and it cares a current I is equal to 2.5 or And Pierre, we need to find a number off down such a dead romantic field, which is we call it to be ex 6.39 times standing power minus for Tesla. It point on the core. Alexis, which is X, is equal to six centimeter from the center off the coil, the magnetic field due to a loop offer radius. Okay. At any point X on the access off The loop is given by B X is equal to, you know in times current A square divided by two times off X square plus a square. Whole trio worked too. Then we saw for a number of town so and will be called to be ex X square, plus a square Altria were due divided by you know I a square next step we substitute the values. Oh, Then we get number off tones to be ah, 69
