Okay, I will be honest, this is a homework assignment. For that matter this is the last homework assignment which is very crucial to preparing for the final. But the problem is I have 2 more finals for which I need to study for. So if you can please help me out and give a detailed solution I will appreciate it. Thanks in advance. A rectangular loop of wire (sides a and b) lies flat in the x-y plane centered at the origin and carries current I in the clockwise direction (viewed from above). Find the magnetic field (direction and magnitude) at the origin.
