A thin straight wire carries a current of 10 mA and makes an angle of 60° with a constant magnetic field of magnitude 10^-6 T. The portion of the wire in this field has a length of 10 cm. Calculate the magnitude of the force on this segment of the wire

Answer 1

A straight wire is placed in a uniform magnetic field of magnitude 0.010 T. The direction of the field makes an angle of 30° with that of the wire, which carries a current of 10 A. What is the magnitude of the force on a 1.0 m segment of the wire? 

Answer 2

Force=current*B*Length*sinTheta whereTheta is the angle between B and current. http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/forwir2.html
