    Deriving Magnetic Field Through Solenoid Using Amperes Law

    I had a long think about the Biot Savert law, and what I can understand from it is the following: It pertains to a length of wire that is so small it can be approximated to be a point the 1/4pir^2 factor is because at a distance r, all of the flux is being spread across the surface of a sphere...
