Question

Why amperes law is not valid for cir cular current carrying coil Ampere s Law is a simple tool for evaluating electrically induced magnetic field at a point For Ampere s Law to be applicable the magnetic field should be in a pattern which creates an Amperian Loop Amperian loop should have the magnetic field strength tangential to the loop or normal to the loop created by the magnetic field around it This loop should also have a non zero or a uniform magnetic field in order to be applicable to Amperian Circuital Law In case of a closed circular loop the magnetic field induced due to the current flowing across the loop does not create such an Amperian loop This is the reason why ampere circuital law cannot be used in circular closed loop although circular loop has symmetrical stucture as the conditions for creating an amperian lo pattern of the induced magnetic field is not satisfied
