It lies in a plane perpendicular to the conductor. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'electricala2z_com-medrectangle-3','ezslot_7',106,'0','0'])};__ez_fad_position('div-gpt-ad-electricala2z_com-medrectangle-3-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'electricala2z_com-medrectangle-3','ezslot_8',106,'0','1'])};__ez_fad_position('div-gpt-ad-electricala2z_com-medrectangle-3-0_1');.medrectangle-3-multi-106{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:15px!important;margin-left:0!important;margin-right:0!important;margin-top:15px!important;max-width:100%!important;min-height:250px;min-width:250px;padding:0;text-align:center!important}. "item": BSCCO/Ag tapes are being developed for electrical power applications at liquid nitrogen temperatures. "position": 2, As the compass is rotated around the conductor, a definite circular pattern will be indicated. The magnetic force on current-carrying conductors is given by. The direction of magnetic field by a current carrying conductor is given as (a)Fleming Left Hand rule (b)Maxwell's Thumb rule (c)Flemings right hand (d)Both (a) and (b) 4.The strength and direction of magnetic field due to a current carrying conductor depends upon (a)Magnitude of current in conductor (b)Distance from conductor The amount of current flowing through a single conductor determines the strength of the magnetic field it produces. magnetic field is the field produced due to flow of charges in conductor carrying current. If less current is passed, there is less deflection in magnetic compass needle.
