Behaviour of Protons, Neutrons and Electrons in Electric and Magnetic fields

The law of electrostatics states that consistently demonstrate that opposite charges attract.

There fore, we deduce with the law of electrostatics:

Protons are positively charged and are therefore attracted to the negative plate in an electric field.

Electrons are negatively charged and are therefore attracted to the positive plate in an electric field.

Neutrons are unaffected in an electric field.

Protons and Electrons will follow circular paths in magnetic fields. The force due to the magnetic field is a centripetal force. Neutrons will be unaffected because it has no charge.
