1. The problem statement, all variables and given/known data Imagine that current flow from east to west. what is the direction of the force on the current when the magnetic field B is (i) to the East and (ii) Vertically up? 3. The attempt at a solution I've done a bit of research mainly from this website http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magfor.html but I am still unclear about how to go about the question. For (i) the magnetic field is to the east, so my fingers are to the right hand side, but my thumb is in the direction of the velocity. Where exactly is the velocity?
