QUESTION 1
A colleague describes to you an engineering diagram (not pictured) that shows a long, straight wire carrying a current of -2.06 A from the bottom of the
page to the top, where a negative value indicates that the current is actually from the top of the page to the bottom. To the right of the first current is a
circular current of -2.27 A in the counterclockwise sense, where a negative value indicates that the current actually flows in the clockwise sense. The
radius of the circular current loop is 4.00 mm, and its center is 5.00 mm from the long, straight wire. What is the component of the magnetic field in the
direction out of the page at the center of the circular current loop? As is very often the case, drawing the diagram is apt to help.
