7. A horizontal wire of length 0.58 m, carrying a current of 7.2 A, is placed in a uniform external magnetic field. When the wire is horizontal, it experiences no magnetic force. When the wire is tilted upward at an angle of 19° it experiences a magnetic force of 4.70 multiply.gif 10-3 N. Determine the magnitude of the external magnetic field.
