I wasn't doing physics before the summer so missed this part of the course.

Apparently your middle finger points in the direction of the current flow (or magnetic induction?). Does is have to point at the exact angle of the current/induction, or just in the general direction (i.e. either up or down)?

Well I would imagine it's intended to be so that it's at right angles, so I doubt it'd be the exact angle of the direction of current flow, just the direction based on the movement and field.

yeah the right hand rule is when you take our right hand , use the r1st three fingers and put them at right angles to each other

as the 3 properties symbolised by your fingers are at right angles to each other

If i am not here i am somewhere else
