Determine the strength of the current passing through a straight conductor in a uniform magnetic

Determine the strength of the current passing through a straight conductor in a uniform magnetic field with an induction of 10, if a force of 20 Newtons acts on a conductor 10 cm long.

Data: V (induction of a uniform magnetic field in which the conductor is located) = 10 T; l (conductor length) = 10 cm (0.1 m); F (value of the force acting on the conductor) = 20 N; we will assume that the conductor is located perpendicular to the lines of induction (α = 90º; sin 90º = 1).

You can determine the current strength from Ampere’s law: Fa = I * B * l * sinα; I = Fa / (B * l).

Calculation of the current strength: I = 20 / (10 * 0.1) = 20 A.

Answer: The current in a straight conductor is 20 A.
