Deflection Of Oscilloscope Beam Using A Magnet


Deflect a beam of electrons. Classes Used: Phys 102, 108

magnetic field, current, oscilloscope Updated on: 06/13/13


To show the force on a beam of electrons when a magnetic field is applied. To show that a flow of electrons is equivalent to a conventional current in the opposite direction.


Oscilloscope with case opened, bar magnet


The special oscilloscope can be set up to show the exposed neck of the tube. When a magnet is brought near the neck of the oscilloscope, the electron beam will move.
