| + | Conceptual Questions: | ||
| + | - How do you decide what the separation vector is for a current wire? | ||
| + | - How do you pick the bounds for the B-field integral? | ||
| + | - What steps do you take to set up the B-field integral? | ||
| + | - How is the magnetic field equation for a current wire similar/ | ||
| + | - How is the right hand rule for a current wire similar/ | ||
| + | - What assumptions did you make in this problem? What are the impact of those assumptions on your solution? | ||

| + | Conceptual questions: | ||
| + | - What is the dl vector and how is it different from the r_sep vector? | ||
| + | - How can you use right hand rule to determine the direction of the B-field from the current loop? | ||
| + | - Why is the magnetic field smaller on the outside of the ring compared to the inside? | ||
| + | - In the real world, why would we want to use a current ring instead of a permanent magnet if we need a B-field? | ||
| + | - The current in this problem is 5000 A. Is that big or small? Is it realistic? How would you create this kind of electromagnet in real life? (Like in the video) | ||
| + | - Why would having a magnetic field from a ring of current attract the chunks of metal from the truck? | ||
| + | - How does the set up from the code compare to the integral set up from Wednesday? Write out the steps that the code takes and compare those to your steps from Wednesday. | ||
