$\cdot$ Two high-current transmission lines carry currents of 25 $\mathrm{A}$ and 75 $\mathrm{A}$ in the same direction and are suspended parallel to each other 35 $\mathrm{cm}$ apart. If the vertical posts supporting these wires divide the lines into straight 15 $\mathrm{m}$ segments, what magnetic force does each segment exert on the other? Is this force attractive or repulsive?

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".

we have a following situation. Two wires a caring the current 75 in piers and are 25 impure, respectively. Um, these are two wires and the car goes in now same direction. The distance between these two wires the 0.35 meter or 35 centimeters. We asked if I what is the force between them and what is the nature off this force? We can write the force between to y skating a current I want tonight to use me, Lord l l will the length of wire. All right. By one times I too, my one is a cramped in one wire. And to use the current the second wire divide by two by are the distance between them. The next step we see, we have a current Stephen Lent is given an RS given, which is the distance between these two wires. Well, simply plug those values and get the answer. So, um, playing those values So we have four by dime, stands about minus seven times 15 times into five in Pearson, 35 appears divided by two pies. A constant times. Is there a 20.35 meter and this gives us a. Force off 0.1607 Newton. And if we just well put this decimal point here than we get down certain he's the report 01 six or one Newton. So this is the force between these two R's, since there wires have brought currently in the same direction, so, um, the force will be attractive attract you.
