The Attempt at a Solution
Alright in the picture you see two hands (YES THEY ARE HANDS).
The one my book says is to use your palm and let your palm be opposite to v and other fingers go into the page and your thumb will tell you your direction of the current.
I have only one problem with this, if my thumb is going up, how am I suppose to tell (quickly without reasoning to changing flux and such) which way will the current flow?
Now for my curling one. Our professor taught us using that, he said to point your thumb into the B-field and curl your fingers and they will be in the direction of the induced current.
Here is my problem. I am curling and I get my induced current to be clockwise, how do I get it counterclockwise? My professor's hand had nothing to do with the velocity
