Determine the magnetic induction of the magnetic field, which acts on a 20 cm long conductor

Determine the magnetic induction of the magnetic field, which acts on a 20 cm long conductor with a current of 0.1 A with a force of 5H.

Given: l (conductor length) = 20 cm (0.2 m); I (current in the conductor) = 0.1 A; F (value of the Ampere force that acts on the conductor) = 5 N; to calculate the magnetic induction, we assume that the conductor is positioned perpendicular to the magnetic field (α = 90º, sinα = 1).

Let us express and calculate the magnetic field induction from the formula: Fа = B * I * l * sinα, whence B = F / (I * l * sinα).

Calculation: B = 5 / (0.1 * 0.2 * 1) = 250 T.

Answer: The induction of the magnetic field is 250 Tesla.
