if a negative charged particle enters a magnetic field perpendicularly,then it follows a circular path.My questn is in what directn does the particle move---in clockwise or anticlockwise???pls provide reasons..

Sir,,,but if we use flemings LHR for a +ve charge and for a field directed into the page,then we would get a clockwise direction i guess......and then a -ve charge will  have a anti-clockwise trajectory (opposite of the positive one).......pls check it Sir...reply soon
