so EK always states you don't need to know the Righthand Rule for magnetic force

Members do not see this ad.

but i will state now that you will since you needed to know it on my old MCAT! since i'm retaking it July 10th, i'm reviewing and realized i missed it. 😉

People will stress to "not" memorize certain things, but if it only takes you a minute to refamiliarize yourself with the idea, then it doesn't hurt to know it. The right hand rule is taught in almost every physics course a premed takes and is remembered forever like the quadratic formula..


But on a light note, how did you know about the question/were you able to review the question?

oh wait...someone please clarify which direction B (magnetic fields) point in. is it a linear direction or CCW/CW?

whenever you deal with F=qvXB, they always point B's direction in a linear direction. however, when they actually draw out the magnetic field, they show it as circular motion. ehh, someone please clarify

I agree. Even if technically, we don't have to memorize the Rhand rule, likely if it comes up in some physics passage, it'll be explained in some really twisted, annoying way. Same goes for the kinematics stuff when it comes up in passage form... much better to just memorize it, instead of depending on the passage. That goes for most of PS, especially physics, in terms of equations, imo. Also, I tend to think that the simpler equations really should be like 2nd nature (memorized) simply from doing so many problems... if they aren't, probably more problems need to be done 😉
