22 de feb. de 2020 · If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole. So, to summarize the magnetic south pole is always clockwise in relation to the positive wire.
What is the direction of the induced current in the loop? (a) clockwise (b) counter-clockwise (c) no induced current I Downward flux through loop decreases, so need to create downward field

By convention, we define positive direction of current to be in the direction a positive charge would move. Electrons (with their negative charge) move in the opposite direction of the positive current arrow. Created by Willy McAllister.
The right hand rule is applied for conventional current flow (opposite the direction the electrons are actually moving). Thus, if you want to use this rule for electron flow, you simply follow the method and then flip the direction.
The right hand rule is used to determine the direction of the magnetic field lines and current around a straight current carrying conductor, solenoid or coil inductor.
Current is directed from the positive red wire to the negative black wire, as shown by the green arrows. At the graphite projectile we notice the current travelling straight to the right, while the magnetic field between the rails is pointing straight up.
