Determine the direction of the magnetic field produced at the labeled positions in the following situations. Shown below is a cross-sectional view of a straight wire oriented perpendicular to the screen, carrying a current out of the screen. Indicate the direction of the magnetic field at a point below the wire, and at a point to the right of the wire. Next, consider a circular loop of wire carrying a clockwise currents as shown below. Indicate the direction of the magnetic field at points both inside and outside of the loop.

Solution

Answer:

(1) Field direction is towards right at a point below the wire

(2) Field direction is towards up at a point right of the wire

(3) Into the screen inside the loop

(4) No field outside the loop
