7A 2.6 m wire carries a current of 2.5 A. The direction of the conventional current is due west. The strength of Earth's magnetic field at the location of the wires 5.0 x 10T and the orientation of the field is north. Both the wire and Earth's magnetic field are horizontal. A (a) What are the magnitude and direction of Earth's magnetic force on the wire? (b) What will the force on the wire be if the wire is rotated to an angle of 72° with the magnetic field?
