By studying the centripetal acceleration of electrons in a magnetic field Thomson was able to successfully determine their charge-to-mass ratio. Thomson's work
Objective To measure the electronic charge-to-mass ratio e/m by injecting electrons into a magnetic field and examining their trajectories. We also estimate
Electrons emitted by the cathode travel radially to the anode (see Figure 1) however in the presence of an axial magnetic field (which can be obtained by
2. To measure the charge to mass ratio of an electron. Theory. When an electron moves in a magnetic field
Experiment objectives: measure the ratio of the electron charge-to-mass ratio e/m by studying the electron trajectories in a uniform magnetic field. History.
This experiment measures e/m the charge to mass ratio of the electron. This ratio was first measured by J. J. Thomson in 1897. He won a Nobel prize for his
