![]() The analogies can only go so far as to describing the physical quantity in question. I hope that you do revisit the definitions after reading the analogies. The ring is coaxial with the axis of the circular coil. What magnetic flux linkage is quantifying is, in a sense, how much the total impact the magnetic field has on the coils, that is, if the magnetic field is passing through $N$ coils, the effect of the field is multiplied $N$ times, and that's why we quantify it as, in this example, $N*BA$. Magnetic flux in a loop from a circular coil Ask Question Asked 5 months ago Modified 5 months ago Viewed 99 times 0 Problem At the center of a circular coil with length L L, radius b b and N N windings is there a small circular ring with radius a << b a << b. Now, to the first ring I add a few more rings, like a solenoid, and I ask, how much flux of water is passing through it? It's going to be W, since adding more rings does not increase how much water is passing though, and analogously, this is what magnetic flux is quantifying - how much magnetic field is passing through. Now, I put a ring with the same radius as the opening of the hose, and I ask what is the flux of water, that is how much water is passing through the ring? Let's say it's a certain amount W. We will let water be the magnetic field in our example. Think of it this way:Ĭonsider a hose that is running. What magnetic flux concerns itself with is how much magnetic field passes through the coil. You might be confused because the flux through one solenoid coil is $BA$, where $B$ is the magnetic field and $A$ is the area, so if you stack a bunch of coils then it should be $N*BA$. Try moving the magnet through a four-turn coil and through a two-turn coil. ![]()
