Biot-Savart and a Rectangular Loop

AI Thread Summary
The discussion revolves around calculating the magnetic force exerted by a current-carrying wire on a rectangular loop using the Biot-Savart Law. The problem involves wire 1 oriented along the y-axis and wire 2 as part of a rectangular loop in the xy-plane. Participants express uncertainty about how to approach the problem, with one suggesting to use Ampere's Law instead of Biot-Savart. Feedback indicates that the approach taken is correct, although further verification is needed. The conversation highlights the challenges faced when tackling complex electromagnetic problems for the first time.

Homework Statement



Consider the figure on the right. Wire 1 is oriented along the y-axis and carries a current I1. A rectangular loop located to the right of the wire in the xy-plane carries a current I2. Find the magnetic force exerted by wire 1 on the top wire of length b in the loop labeled, "Wire 2" in the figure.

Remember dF = i dl x B ?
i = current
dl =differential length expressed as a vector.
For B try ampere's law. Forget Biot-Savart.
 
Okay, I tried this. Does it look right?

It's too late tonite for me to check it in detail but your approach is spot-on.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
