A horizontal wire of length 0.14 m, carrying a current of 7.7 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 29°, it experiences a magnetic force
of 5.5 × 10-3 N. Determine the magnitude of the external
magnetic field.
