Can someone tell me what direction my thumb and fingers should point when answering this question?
I'm not understanding what the arrows mean in relation to into and out of the page in the answers. I understand that if the field is going into the page on the right, and out of the page on the left, and it is wrapping around the field within the solenoid (since the coils make a circle), but what do the arrows in the answer represent?
Thanks!
