Trajectories in Electric and Magnetic Fields

Description

The Trajectories in Electric and Magnetic Fields model computes a family of trajectories of charges emitted from a point source isotropically and with the same energy. These trajectories create focal points and caustic surfaces meeting the symmetry line in conical cusps. The simulation enables users to study these trajectories in both crossed and parallel magnetic fields. The user can vary the initial particle velocity and the field strengths.

The Trajectories in Electric and Magnetic Fields Java model was developed by Wolfgang Christian using the Easy Java Simulations (EJS) modeling and authoring tool created by Francisco Esquembere in Murcia, Spain. It was later converted from Java to JavaScript by Wolfgang Christian and Robert Hanson using the SwingJS system developed by Hanson and his students at St. Olaf College.
