@@user-th8pr7no5p the one cancelling out is the one for half a loop of wire whose distance would be pi*R but the one for a wire bent through angle theta only has a distance R*theta in radians hence there is no pi to be cancelled out meaning the magnitude of B would be (mu*I*theta in radians)/4*pi*R

The AP Physics E&M exam is today in a few hours. I was freaking out the first few periods of school and since I was excused I left early to study and to calm down. I’ve been watching your videos since this morning for a quick review and you’re amazing at explaining the topics in quick and easy to digest ways! Some things are finally starting to click! I don’t know if I’m still gonna get higher than a 1 or 2 as it’s been a rough year calculus-wise since I’m only in pre-calc so you can imagine how some things were difficult to pick up, but at the moment, these videos are easy to follow along to and give me some hope. Thank you so much for taking time to make these💖

0:40 I think if you are considering the cross product between dL and r, then the denominator should be r cubes, if it were a simple multiplication sign, then sin theta is ommited, either way. Being a student, I might be wrong, kindly correct me, if I am at fault.

It’s between Dallas and r hat. R hat has magnitude 1. If I wrote it as dL cross r then yes you’d write it as r cubed in the denominator. I’m pretty sure I talk about this in the video though, maybe not

Great video! At 6:55, though, I believe the resultant magnetic field due to the current is drawn in the wrong direction. If the current is pointing to the right, by the RHR, the magnetic field should curl in a circle towards us rather than away from us as shown in the video. (Unless I misunderstood what the arrows were representing)

@WeAreShowboat

@@maxsolomakha4447 That’s a great point. You’re right. The absolute value of an integral is not equal to the integral of the absolute value of the integrand if the integrand changes sign. So you just have to break the integral up into pieces which have different signs and subtract. Like what I do for the loopy one at 15:23. So this approach still works you just have to be careful not to add pieces which are actually cancelling each other out.
