Determine the current strength if the length of the conductor is 4 cm, the magnetic induction is 0.05 T.

Determine the current strength if the length of the conductor is 4 cm, the magnetic induction is 0.05 T. the force acting on the conductor is 0.06 N. The angle between the induction vector and the direction of the current is 90 degrees.

Data: l (conductor length) = 4 cm (0.04 m); B (value of magnetic induction) = 0.05 T; F (force acting on the conductor) = 0.06 N; α (angle between induction vector and current direction) = 90º.

The current strength is determined from Ampere’s law: Fa = I * B * l * sinα and I = Fa / (B * l * sinα).

Calculation of the current strength: I = 0.06 / (0.05 * 0.04 * sin 90º) = 30 A.

Answer: The estimated current in the conductor is 30 A.
