What is the strength of the current passing through a rectilinear conductor located perpendicular

What is the strength of the current passing through a rectilinear conductor located perpendicular to a uniform magnetic field, if a force of 20 N acts on the active part of a conductor 40 cm long at an induction of a magnetic field of 10 T?

In this task, we will use the usual Ampere force formula F (A) = B * I * L * (Sin = 1), from here we need to express I = F (A) / (B * L) and we get that the current strength equals 20 / (10 * 0.4) = 5 A.
