A 3.5 m wire carries a current of 5.5 A. The direction of the conventional current is due west. The strength of Earth’s magnetic field at the location of the wire is 6.0 x 10-5 T and the orientation of the field is north. Both the wire and Earth’s magnetic field are horizontal. (a) What is 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 720 with the magnetic field?

A current-carrying wire is in a B-field and experiences a magnetic force (FB>0). The magnetic force vector is shown below. Choose all the arrows that could represent the current direction. Magnetic force Current direction 45° 45° 45* 45° 45° 40 45° 45°
