+ | - What is the right hand rule for the magnetic field from a current-carrying wire? What is the right hand rule for the magnetic force on a current-carrying wire? | ||
+ | - Suppose you have a single straight wire with a current. That current will create a magnetic field. Will that magnetic field exert a force back on the current? Why or why not? | ||
+ | - Way back from Physics 1 - how does velocity relate to acceleration? | ||
