Question #26630
why cathode rays get deflected towards north pole in presence of magnetic field?
Expert's answer
Cathode rays are electron beams. When they are moving in a magnetic field, they are deviated. The direction of their deflection is given by Fleming's left hand rule. The direction of deflection, current (which is the reverse of the direction of the electron beams) and field are all perpendicular to each other. Hence, the electron beam will deviate in a direction contained in a plane which is perpendicular to both the field and the electron beam. Hence, the cathode rays are neither deflected to the north nor South Pole.
