use ampere circuital law to find magnetic field due to straight infinite current carrying wire how are the magnetic field lines different from the electrostatic field lines
Dear Student ,
Let the current through the long straight wire is I and here from the wire at distance r at point P we have to find the magnetic field .
Taking the circular path as the Ampere's circle then we get that dl is parallel to B at every place applying the cork screw rule .
Therefore , here applying the Ampere's circuital law we get ,
Difference between the electrostatic field lines and magnetic field lines :
(i) The main difference between the electrostatic field lines and magnetic field line is the magnetic field lines start from north pole and end at south pole where as the electric field lines can generate from a positive charge to a negative charge .
(ii) Electric field lines can not stay in the hollow conductor .But the magnetic field lines can stay in the hollow magnetic substance or magnetized substance .
(iii) For an isolated charge electric field lines can be seen but an isolated magnetic pole can not be generated and also the field lines can not be generated .
Hope this helps you .
Regards
