Question

State the formula for magnatic induction at a point due to a straght current carrying conductor

Answer 1

in 1819 scientist H.C. oerstead read in the school of Denmark investigated and get the result when the electric current pass through the conducting wire a magnetic field is produced a region around its so the magnetic field equals to one upon distancethe magnetic field produced due to the current through the conducting wire is directly proportional to the current carrying conductor wire the( magnetic proportional field Alpha electric current)
