An electromagnet produces a magnetic field of 0.580 T in a cylindrical region of radius 2.90 cm between its poles. A straight wire carrying a current of 10.9 A passes through the center of this region and is perpendicular to both the axis of the cylindrical region and the magnetic field. Required:What magnitude of force does this field exert on the wire?
