Task 2.77
A conductor with a current of 1 A, 0.3 m long, rotates uniformly about an axis passing through its end in
Plane perpendicular to the lines of induction of a magnetic field of intensity 1 kA / m. For one
Minute of rotation, the work is 0.1 J. Determine the angular velocity of rotation of the conductor.
