Flux method

Alright kiddo, have you ever noticed how water flows from one place to another? Imagine you have a cup of water and you pour it on a plate. The water is spreading out in all directions, right? This spread of something is called a flux.

Now let's talk about flux in math. In math, we use flux to describe how something is flowing through a surface. It’s like drawing a fence around something and observing how much is going in and how much is going out.

The Flux Method is a way of finding out how much 'something' is passing through a surface at a particular point in time. To do this, we look at how many 'lines' or particles are crossing the surface at that point.

Imagine 'lines' flowing through space, kind of like how water flows in a stream. We can count how many lines are passing through each part of a surface at a particular moment, just like in the water example above.

The Flux Method is particularly useful in the field of physics, where we use it to understand how things like electricity, magnetism, and gases behave in space. The flux method helps us make sense of things like, why do magnets stick to the fridge, or how can we measure the flow of air in a room?

So, Flux Method is a way of understanding how much of something is passing through a surface at a point in time by counting how many particles or lines are crossing that surface. It's pretty cool, huh?
