- | * The current is steady, and the wire segment is uniform. | + | * The current is steady: This means the current is not changing with time or space through our segment |
+ | * The segment is straight and uniform: This will simplify down our model to where the segment only extends in a single direction, simplifying the separation vector. Also, assuming | ||

+ | You can try to do this by adjusting your x-y coordinate system as well (this is in the example video), and you will get the exact same solution. This is a great way to get some practice solving these problems and it gives you other solutions to check your answer with. |
