Fields and SheetsFields and SheetsThis model represents the interaction of the electromagnetic fields of two charged particles. The effective charge at any given point around the particles can be determined by taking the sum of the (directional) charges of both particles at that point.
The primary elements of the model are the two charges and their x- and y-components. These charges can be manipulated in order to view the charge fields of different charge configurations.
To use this model, simply set the two charges along with their x- and y-components and then press [Ctrl] [=] to refresh. The first Excel sheet shows the electrical field of the superposition of the two charges. The second and third sheets show the x- and y-components of that selfsame field, respectively.
As one charge increases, its representation will be larger. If one charge is sufficiently larger than the other, it may overwhelm that charge to the point that only one circle is visible.
