A straight conductor with a length of l = 20 cm is placed in a uniform magnetic field with an induction of b = 0.1 T (the lead wires are outside the field). Determine the force F acting on the conductor if a current flows through it I = 50 A, and the angle between the direction of the current and vector of magnetic induction 30 *.

To find the value of the force (Ampere force) acting on the specified straight conductor, we use the formula: Fa = I * B * l * sinα.

Data: I – current in the specified straight conductor (I = 50 A); B – induction (B = 0.1 T); l is the length of the straight conductor (l = 0.2 m); α – angle between current and induction vector (α = 30º).

Calculation: Fa = I * B * l * sinα = 50 * 0.1 * 0.2 * sin 30º = 0.5 N.

Answer: A force of 0.5 N. acts on the indicated straight conductor.
