Question

upward 12) Avertical wire Carries current straight up in a region where the magnetic field Vector fonts toward the north. What is the direction of the magnetic free on this wone A.) downward Bij toward the northe C) toward the East Di) toward the west F.) toward the South

Answer 1

Solution A vertical wise cancies a current straight up in a region where the magnetic field vector points toward the north. Uniform Magnetic field in worth olisection 110111 E wat S This represent the vertical wire carries a current straight up. Direction of Magnetic force on this wire is given by Right hand rule -1. In this rule thumb of right hand is in the direction of current. Then fingers in the direction of magnetic field. Then perpendicular to the palm points in the direction of magnetic force. thumb will coming out ferpendiculas to the plane of paper in the direction of current and fingers will be in north direction in the direction of magnetic field. Therefore magnetic force will be perpendicular to the palm, which is in the silth Soulth direction. West direction. Hence direction of Magnetic force is West. Correct Answer D) Toward the west. In our case ,
