I'm having a bit of confusion applying the left hand rule to find the direction of electron flow in a coil. I'm given the following pictures. 1.) To use the left hand rule here, I would wrap my hand around the object with my thumb pointing towards the north pole, so my fingers would indicate that the electrons are flowing from right to left. Is that correct? 2.) For this second one, the electrons are flowing from left to right? Next, I am asked to indicate the location of the north pole on the following diagrams. 3.) Is the north pole on the right side here? 4.) Here, the electrons leave the short bar and travel from the bottom to the top. So then the north pole is located at the top of the bar?
