In a magnetic field with an induction of 2 T, a conductor with a length of 1 m is placed through which a current of 10 amps flows. Find the force acting on the conductor.

On a conductor of length L, through which a current flows with a force I, in a magnetic field with induction B, a force F acts, which is called the Ampere force, and it is calculated by the formula: F = B ∙ L ∙ I ∙ sinα, where α is the angle between the directions current and magnetic field.
From the condition of the problem it is known that a conductor with a length of L = 1 m, through which a current of I = 10 A flows, is placed in a magnetic field with an induction of B = 2 T. Let us take sinα = 1, since the condition does not say about the relative position of the conductor and the direction of the field, then we find the maximum value of the Ampere force: F = B ∙ L ∙ I. Substitute the values ​​of physical quantities in the calculation formula and make calculations: F = 2 T ∙ 1 m ∙ 10 A; F = 20 N.
Answer: a force of 20 N acts on the conductor.
