Motor Effect

Motor effect on a wire applet
This Java applet demonstrates the Lorentz force, exerted on a current-carrying conductor swing in the magnetic field of a horseshoe magnet.

The Motor Effect/Third Left Hand Rule
This website will make an excellent resource for students preparing for a magnetism exam. It explains in comprehensive detail how to track the current in a wire, and uses cross sectional diagrams much clearer then the ones found in ourtextbook. This website also explains how to use the third left hand rule to your advantage, as well as showing a labelled diagram of a motor. This website is an excellent alternative to studying from a textbook.

Electric motor applet
This Java applet shows a direct current electrical motor which is reduced to the most important parts for clarity. Instead of an armature with many windings and iron nucleus there is only a single rectangular conductor loop; the axis the loop rotates on is omitted.

Motor Effect
This page shows you how to build a device that displays the "Motor Effect" using common household items. It then explains what is happening in the device by using the "Left Hand Rule", which allows you to find: electron flow, direction of the magnetic field or the force exerted on the wire.

Charged Particles in a Magnetic Field

In this Applet particles are entering the region of the magnetic field with their velocities being perpendicular to the magnetic field lines. JavaPhysMath Applets copyright
