| GUIDES | ||
| 1 | Magnetic Fields 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.] |
|
| 2 | Magnetic
Force Magnetic force on a current-carrying wire and the Lorentz force on a moving charged particle. |
|
| 3 |
Mass Spectrometer Electric and magnetic fields can used to sort out a spectrum of molecules. The process is quite clever. |
|
| 4 |
Induction How voltage is induced by using a magnetic field. |

| JOBS | ||
| 1 |
Right
Hand Rule [Lab Springboard] at TPT Constructing the right hand rule from lab experience. |
|
| 2 | Directions
[Job] at TPT The geometric relationship between electric current, magnetic field, and magnetic force. |
|
| 3 | Motional
EMF [Springboard] at TPT 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
Magnetic Flux? [Springboard]
at TPT The concept of magnetic flux is useful when exploring induced electromotive force (voltage). |
|
| 5 | Faraday's
Law [Springboard] at
TPT Getting from Blv to delta phi / delta t takes a bit of doing, so let's do. |

Bobbing for Magnets This is a grandaddy! Electromagnetic force, induced emf, and "magnetic pendula". |

Genecon-Capacitor
Conundrum Crank the Genecon to charge the 1-farad capacitor. Then let the handle go for a big surprise! |
