3.4 The following scheme shows an experimental setup with which the specific mass of electrons can be determined. hot cathode UB Cover I Condensator magnetic coil a) Draw the magnetic field lines in the picture. Furthermore, assume that the magnetic field is homogeneous. b) Let UB = 1000 V and B = 0.1 T. What amount must have so that the electrons fly straight? c) Suppose the magnetic field is not generated by Helmholtz coils, but by a continuous coil with length l = 0.1 m and a number of turns of n = 500. How large must the current I be chosen to reach 0.1 T?
