Nature and interaction of electric forces and magnetic forces are briefly explained. At zero gravity distance, electric fields do not interact and interactive force reverses on either side of this distance. Nature and interaction of nuclear forces are explained in a later chapter. This chapter also gives brief out line on determining strength of natural forces. Electric charges are nothing but relative direction of electric fields.
Positrons have distinct north magnetic polarity and electrons have distinct south magnetic polarity.
Positrons and electrons have opposite nuclear fields. Because of its nuclear force electrons are unable to form group with any other particle. A positron with single neutron-like shell is a proton. If positron has two neutron-like shells on either side of its equator, it becomes a deuteron. Anti-matter and annihilation of matter is also briefly explained.
