Describes the magnetic field created by a current through a wire and the effects of a magnetic field on charged particles that move within the magnetic field.
Understand how magnetic forces applied to charges in motion generate circular (centripetal) motion, and how the paths these particles leave provide insight into their nature.
The right hand rule is explained for the case of a charge particle entering a magnetic field. The radius of the loop is derived for this scenario.
The force on a moving charge particle in a magnetic field is demonstrated and explained here using an electron laser and Helmholtz coils.
Demonstrates the force created by a current moving through a magnetic field.
Use the right hand rule to determine the magnitude and direction of the force of a B-field on a current-carrying wire.
Reviews why magnets work and problems involving magnetic interaction and electron movement.
A list of student-submitted discussion questions for Lorentz Force.
Discover how traffic lights know when to change.
This study guide reviews electromagnetism concepts: magnetic field and field lines, first right hand rule, magnetic flux, solenoid, electromagnetic induction, force on charged particle, second right hand rule, and inductance.
