Current flows along the rectangular frame. frame length 10 cm width 15. the frame is placed in a magnetic field with an induction of 0.4 T, a torque of a pair of forces of 5 mN * m acts on the frame.

It is known from the condition that the current flows along a rectangular frame with dimensions: length – 10 cm, and width 15 cm.

In addition, we know that the frame is placed in a magnetic field with an induction of 0.4 T and, in addition, a torque of a pair of forces of 5 mN * m acts on the frame.

Let’s apply the formula to calculate the current strength:

B = M / (I * S);

We express the current strength:

I = M / (B * S);

We find the area of the frame as the area of the rectangle:

S = a * b.

We substitute in the formula for calculating the current strength I = M / (B * a * b).

It remains to substitute the values into the formula and perform calculations:

I = (5 * 10 ^ -3) / (0.4 * 0.1 * 0.15) = 0.83 A.

Answer: I = 0.83 A.
