Charged Particles in Magnetic Fields

Synopsis: Examines moving charges within a magnetic field by studying auroras. Demonstrates that moving electric charges experience a force in magnetic fields, and explains how to quantify this force and find its direction using hand rules. Links centripetal force to the magnetic force using particles within a cathode-ray tube. Applies electromagnetic principles in several types of technology.

Title: Coulomb’s Law
Synopsis: Demonstrates how to verify Coulomb’s Law using a torsion balance in a quantitative analysis of the relationship between charge, distance and electrostatic force. Analytically compares Coulomb’s Law of Electrostatic Force and Newton’s Law of Universal Gravitational Force. Shows how to solve electrostatic force between point charges using Coulomb’s Law and vectors.

Title: Coulomb Forces in Nature
Synopsis: Demonstrates a real-life application of quantifying electrostatic forces between point charges using ionic crystals. Uses large-sized models to demonstrate advanced Coulomb’s Law problem-solving, using vectors and vector components. Introduces the need to accept uncertainty in describing and explaining electrical phenomena.
