PURPOSE: Three-dimensional model to aid in visualization of the electric field of a ring of charge.
DESCRIPTION: This is a non-working model for the electric field of a ring of charge. It shows explicitly the fields of two opposite segments of the charged ring, along with the vector sum of the two fields. This shows how two opposite sides cancel, leading to the field vector shown on the model.
REFERENCES: (PIRA unknown.)
EQUIPMENT: Model as photographed.
SETUP TIME: None.
