In a uniform magnetic field with an induction of 0.82 T, there is a straight conductor with a current of 18 A

In a uniform magnetic field with an induction of 0.82 T, there is a straight conductor with a current of 18 A, located perpendicular to the lines of magnetic induction. Determine the force acting on the conductor if its length is 128 cm.

Given: B (field induction) = 0.82 T; I (current in the taken straight conductor) = 18 A; the conductor is located perpendicular to the lines of induction (sinα = 1); l (length) = 128 cm = 1.28 m.

To find the magnitude of the force acting on a taken straight conductor, it is necessary to apply Ampere’s law: F = B * l * I.

Let’s make a calculation: F = 0.82 * 1.28 * 18 ≈ 18.89 N.

Answer: A force of 18.89 N should act on the taken straight-line conductor.
