What is Flux ?

What is flux? An imagining line of force created by magnet.
Why it travel from N pole to S pole? Why even it can travel from S pole to N pole, because this two pole has equal magnetic strength, did really flux travel from one pole to other? No, 100% wrong flux will not travel from N pole to S pole.

Flux is resultant force created by atomic magnetic force of magnet
Flux is a two imaginary line of force created by North Pole of the magnet
and South Pole of the magnet.
The job of flux is to collect near by like amf to support his primary amf. This Collection of amf will create the pulling or attraction in near by magnetic material.

Two type of Flux

North Pole (Namf) created its own North Pole flux to collect near by like amf from near by magnetic material.
 Like wise South Pole (Samf) created its own South Pole flux to collect near by like amf from near by magnetic material. So magnet has two different magnetic flux areas. Ok what happens at middle or contact area of this two different flux (N & S flux), the middle area is called as equator area.
