Determine the direction of the magnetic field lines produced by the following current-carrying straight conductors. The arrow or "x" indicate the current flow. Draw the magnetic field. Provide a brief explanation of your answer. (Which RHR was used, etc...) Solution: Solution: Determine the direction of conventional current flow in the following diagrams where magnetic field lines are indicated by an arrow, a dot, or an "x" depending on their direction. Provide a justification for your choice. Solution: Solution: Determine the direction of the magnetic field produced by the current flowing in the following solenoids, by labelling the magnetic poles (N or S) in the correct locations. Be sure to note subtle changes in the direction of the coil windings and the cell orientation. Provide a justification for your choice. Solution: Solution: Determine the orientation of the battery cell (add + and - to the battery) in the following solenoids such that the current produces the magnetic field shown. Provide a justification for your choice. S Solution: N Solution: N ? ? S
