1.An electron beam is moving horizontally towards east. If this beam passes through a uniform magnetic field directed upward then in which direction will the beam be deflected?
2.If a proton be moving vertically upward and the magnetic force on it acting towards north in a horizontal plane, then what will be the direction of the magnetic field?

Right hand rule:
direction of velocity of positive charge : Index finger
direction of magnetic field : middle finger
direction of force : thumb
1. According to right hand rule, a proton would deflect to south direction. But the charge carried by electron is negative. So it will be deflected towards North.
2.Using right hand rule, the direction of magnetic field would be towards East.
