1. The problem statement, all variables and given/known data polarity of a horseshoe shaped solenoid given symbol for power source large line small line. Current flows through the right end of the horsehoe and out of the left end. The wire is wrapped in a CW direction if looking at the left end of the magnet. The wire is wrapped in a ACW direction if looking at the right end of the magnet. Im confused that the current direction using right hand grip rule and wrap direction of the coil viewed from the ends are giving the opposite conflicting result. 2. Relevant equations none 3. The attempt at a solution Assuming conventional current from positive (large line) to negative (small line). Viewing the right end current direction is ACW so this should be North Viewing the left end current direction is CW so this should be South Is this correct or should I consider the rules as if the horseshoe was broken in half like a wishbone? Thanks..
