Задача 30748.

In an electromagnetic pump for pumping molten metal, the pipe section with metal is in a uniform magnetic field B. The magnetic field induction is 0.1 Tesla. A current of 100 A is passed through this section in a direction perpendicular to vector B and to the pipe axis. Find the excess pressure created by the pump. The cross-section of the pipe is a square with a side of 2 cm.
