Expert Answer:

According to Biot Savart's Law, the magnetic field at a point P due to current element AB of conductor XY carrying current I making angle ? with depends upon the following factors    

                                                                                                  

i.         

ii.        

iii.                                                                                          

iv.                                                                                                                

Combining these factors                                                     

                                                          

 

K= constant of proportionality.

In S.I units

In cgs units K=1

 

In S.I units, equation 1 can be written as
