Whatare thefactors on whichthe forceactingon a givecurrent- carryingconductorplaced in a magneticfield depend ? State when is the magnitudeof force highest .

Answer»

Solution :Force on the givenconductor ( and hencethe displacmentof the conductor) depends upon :
(1) directionof current and .
(2) directionof magnetic FIELD .
Experiments haveshown that the MAGNITUDEOF theforce is thehighest( or thedisplacement of the rodis LARGEST) when the directionof current is at right angle to the DIRECTION of the magnetic field .
