+  - What is the equation for magnetic force on a current wire? How is it similar/different from the magnetic force on a point charge?
+  - What is the equation for magnetic field on a very long wire? When would you want to use the integral version and when is it ok to use the long wire equation?
+  - If you use the magnetic field equation for a long wire, how do you determine the direction of the magnetic field?

+==== Wrap Up Questions ====
+  - In order to simplify $\vec{F} = \int I d\vec{l} \times \vec{B}$ to $F = ILB$ there are several **critical** steps that you have to take. What are those steps that you need to simplify the force equation?
   - In your calculations, you used dl or L a couple of times. What equations did you use with lengths, and which lengths were they referring to?
   - If the wire has $0.008 \Omega/m$ resistance, how big of a power supply would be required for your current? (Calculate this!)
   - What would change about your solution if the currents went in the same direction instead of opposite directions?
   - What assumptions did you make in this problem? What are the limitations of your solution?
-  - When do you want to use the integral form of the B-field equation? When can you use the long wire equation?
   - How does this relate to real power lines? Do we actually use 1000 A of current in real power lines? (You may have to do some googling here.)
