Deflection Of An Electron Beam By An Electric Field Lab Report, pasadena. J. edu In the experiment the study of magnetic deflection of electrons using the same CRT was used to study electric deflection. If not, the polarity of the Helmholtz coils must be reversed. In electromagnetism, electrostatic deflection refers to a way of This magnetic field deflects the electron beam in a circular path. Experiment 4 uses an electron beam in a vacuum to show Ideally, the electrons will have zero velocity in the x and y directions perpendicular to the z axis on leaving the gun, but the earth’s magnetic field may give the beam some deflection. s a magnetic force or magnets cause an electric force. By measuring the accelerating potential, the current to the coils, and the radius of the circular path of the electron beam, e/m is Introduction The deflection of charged particles in electric fields is a fundamental concept in atomic structure and chemistry. This can be used as a confirmation of the negative charge of the electron, The discussion centers on calculating the deflection of an electron beam in an electric field created by parallel plates. Beams of electrons can be deflected in an electric field (in parabolas).
