In a homogeneous magnetic field with an induction of 0.12 T at an angle of 30 degrees to the direction of the field

In a homogeneous magnetic field with an induction of 0.12 T at an angle of 30 degrees to the direction of the field, a conductor with a current of 1.5 m is located. Determine the current in the conductor if a force of 1.8 H.

To calculate the value of the current in the conductor used, it is necessary to apply the formula: F = B * l * I * sinα, from where we express: I = F / (B * l * sinα).

Data: F – acting force (F = 1.8 N); B – induction (B = 0.12 T); l is the length of the conductor used (l = 1.5 m); α is the angle between the used conductor and the induction lines (α = 30º).

Calculation: I = F / (B * l * sinα) = 1.8 / (0.12 * 1.5 * sin 30º) = 20 A.

Answer: A current of 20 A flows through the conductor used.
