An X-ray beam can be deflected by :

X-rays are a form of electromagnetic radiation, characterized by high energy and very short wavelengths. Unlike alpha or beta particles, which are charged, X-rays consist of photons that carry no electric charge.

• Electric Fields: Exert force only on particles with a net electric charge.
• Magnetic Fields: Exert force only on moving charged particles (Lorentz force).

Since X-rays are electrically neutral, they do not interact with external electric or magnetic fields in a way that causes deflection. They travel in straight lines through these fields. This property was one of the key observations that helped scientists distinguish X-rays from cathode rays (electrons) during their initial discovery. Therefore, they are deflected by neither an electric nor a magnetic field.
