Chapter 7 - Magnetism
| Term | Definition |
|---|---|
| Magnetic fields are measured in | Tesla = E4 Gauss |
| F | = qvB sin theta = mv^2/r |
| If v and B are parallel | Force = 0 cuz sin 0 degrees = 0 |
| If particle is negative, right hand rule | results are the opposite of the correct answer |
| r | = mv/qB |
| Current I | delta q/delta t in Ampere A; opposite of e- flow |
| F (current) | = LIB |
| B for straight wires | = mu I/2(pi)r |
| B for circular loops | = mu I/2r |
| Loop rule | fingers curl in direction of I and thumb = direction of B |
