For some reason I can't wrap my head around the stupid arse "right hand rule", this is the one spot in physics UG I struggled with too.
So far both EK and TBR have failed me when it comes to EMF. Anyone know of any good online lectures for EMF?
 
I don't know any good online lectures, but the way i remember the right hand rule is:

- your thumb looks like a small wire that current runs through, so point thumb in direction of current
- your fingers are like the field lines, so they point in the direction of the electric field
- and the force is whichever direction your palm is going to smack into now that you set up the other two variables.
 
Thank you very much, and sorry about that S2, after I submitted I thought "that probably should have went in the Q&A section".
 
Remember that there are multiple right hand rules. When it comes to understanding Magnetic Force = yes, the palm is pointing in that direction. If you are interested in the force on a electron, you can still use the right hand, just reverse the magnetic force direction. Left -- > Right, Up --> Down, Into page --> Out of page. Or you can use the left hand with the same idea but no reversing the forces.

Another huge right hand rule is understanding the rotation of the magnetic forces when a current is accelerated in a wire. This requires the 👍 (clinched fist with thumps pointed out). This time, point the thumb in the direction of the current, and "grab" on the wire much like 👍. How ever the rest of your fingertips are pointed, that indicates whether it is clock wise or counter clock wise. Play with your hands, and you'll get it figured it out. Example, if the current of the wire is pointing say from your computer screen to your eye. Make a 👍 and point the thumb to your eyes. You'll notice the rest of your finger tips are pointing (curled) in a counter clock wise motion, therefore that is the direction of the magnetic force.

Hope that helps, and someone above has sort of explained the standard right hand rule, if you need more help check out the links or you can PM me. GL with the studies, as I am in the midst of it also.

Thanks, I think this is where I got confused when going through physics as the class just smooshed magnetic fields in with current and suddenly I had two right hand rules applying to the same chapter. I guess to this day my brain still hasn't separated the two
