Vedclass · Answer

(B) The correct matches are as follows:$(A)$ Fleming's left hand rule is used to determine the direction of the force on a current-carrying conductor in a magnetic field. Thus,$(A)$-(iii).$(B)$ Right hand thumb rule is used to determine the direction of magnetic field lines around a current-carrying conductor. Thus,$(B)$-(iv).$(C)$ Biot-Savart law is used to calculate the magnitude and direction of magnetic induction due to a current element. Thus,$(C)$-(ii).$(D)$ Fleming's right hand rule is used to determine the direction of the induced current in a conductor moving in a magnetic field. Thus,$(D)$-$(i)$.Therefore,the correct matching is $(A)$-(iii),$(B)$-(iv),$(C)$-(ii),$(D)$-$(i)$,which corresponds to option $(b)$.
