What if anything is wrong task on the magnetic field of a long straight wire
A wire oriented perpendicular to the page carries a current. The compass can be dragged around the wire to map the field.
A student experiments thoroughly with the compass and decides that the magnetic field lines form concentric circles oriented as shown in the figure below. What if anything is wrong with the students answer?
Carefully explain your reasoning.
You can check the students answer by double clicking in the animation to draw field lines.
