+ | - 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? | ||

You decide to construct makeshift launcher that usies magnetic force to launch projectiles so that they will leave the launcher at a speed of $300 \;{\rm m/s}$. You must construct your launcher on the floor of the laboratory and position it at an angle of 63 degrees so that it is firing out of the window of the laboratory. | You decide to construct makeshift launcher that usies magnetic force to launch projectiles so that they will leave the launcher at a speed of $300 \;{\rm m/s}$.
