Explain biot savart in physical terms ?

Current carrying conductor produces a magnetic filed around it. The Biot–Savart law is used to compute the magnetic field generated by a steady current, i.e. a continual flow of charges, for example through a wire, which is constant in time and in which charge is neither building up nor depleting at any point. It gives us an idea about the strength of the field produced by the current and the direction of the magnetic field. You can y understand the mathematical form only if you have a basic idea about Integration in mathematics. It says that the magnetic field produced is varies as proportional to the current through the conductor and inversely proportional to the square of the distance. is it ok you ?
