A 2.0-m wire carries a current of 15 A directed along the positive x axis in a region where the magnetic field is uniform and given by Bx = 30 mT and By =-40 mT
2. A 2.0-m wire carries a current of 15 A directed along the positive x axis in a region where the magnetic field is uniform and given by Bx = 30 mT and By =-40 mT. Show that the resulting magnetic force on the wire is 1.5 N pointing into the paper. [Please show a diagram for the direction!]
4. Show that a current of 75 A must be maintained in a square loop (50 cm on a side) to create a torque of 1.0 N·m about an axis through its center and parallel to one of its sides when a magnetic field of magnitude 70 mT is directed at 40° to the plane of the loop.
