Question

Which rays deflect the most in electric or magnetic field?

• A. Alpha
• B. Gamma
• C. Beta
• D. X

Answer 1

The correct option is C Beta

Alpha rays are doubly ionised helium nuclei. Beta rays are simply a stream of electrons, while gamma radiation is uncharged electromagnetic radiation. Due to the magnetic effects of electric current, we know that electric current can change its direction in the presence of magnetic field. $\gamma$ radiation has no charge, and hence, it is unaffected by the magnetic field. $\alpha$-particles are simply nuclei (protons and neutrons) and have no electrons in them. Stil, they can be affected a little by magnetic field. However, $\beta$-particles, which are simply electrons, are affected by magnetic field the most.
