When do you use your right hand for the RH rule and when to use your left hand for the LH rule. I'm just havinf second thoughts about this one. I cant remember which one to use in certain cases. when a point charge is moving through a magnetic field depending on wether it is positively or negatively charge which hand do you use to get the direction of the force on the charge if you have the direction of the magnetic field and the velocity of the charge. say they charge is + and the magnetic field is into the screen and the point charge is moving down the page. which hand rule do you use. and the same question but for a -(negatively) charged point charge.
