Why are cathode rays considered to be a stream of electrons?

Q. A beam of cathode rays moves from left to right in a plane of the paper and it enters into a uniform magnetic field acting perpendicular to the plane of the paper and inwards. Now, the cathode rays are deflected :

Q. A beam of cathode rays is subjected to crossed electric (E) and magnetic fields (B). The fields are adjusted such that the beam is not deflected. The specific charge of the cathode rays is given by :

The electrons in an electrolytic cell move from cathode to anode and also in a cathode ray experiment the cathode rays move from cathode toanode. So why we have to create an electromagnetic feild for just knowing th charge of the atoms?
