Descriptions and equations for magnetic field strength near a current-carrying wire, loop, and solenoid. [I've allowed this one to lapse. No need for equations beyond that for a long, straight wire.]
Magnetic force on a current-carrying wire and the Lorentz force on a moving charged particle.
Electric and magnetic fields can used to sort out a spectrum of molecules. The process is quite clever.
How voltage is induced by using a magnetic field.
Hand Rule Lab Springboard - Answers
Constructing the right hand rule from lab experience.
PhyzJob - Answers
The geometric relationship between electric current, magnetic field, and magnetic force.
|3||Motional EMF Springboard
When a wire is moved through a magnetic field, a voltage might be induced. How much? Just the right amount, if you know what I mean!
|4||What is Flux? Springboard
The concept of magnetic flux is useful when exploring induced electromotive force (voltage).
|5||Faraday's Law Springboard - Answers
Getting from Blv to delta phi / delta t takes a bit of doing, so let's do.
|LABS - DEMOS
This is a grandaddy! Electromagnetic force, induced emf, and "magnetic pendula".
Crank the Genecon to charge the 1-farad capacitor. Then let the handle go for a big surprise!
