In a uniform magnetic field, the induction of which is equal to 980 mT, a coil of 230 vit.

In a uniform magnetic field, the induction of which is equal to 980 mT, a coil of 230 vit. The axis of the coil is parallel to the lines of induction of the magnetic field and the radius of its cross-sectional field is 8 cm. Determine the flux linkage of the coil.

To solve this problem, you need to use the following formula:
F1 = B * s;
You need to find s, using the following formula:
s = pi * R ^ 2;
Let’s substitute:
s = 3.14 * 64;
s = 200 cm2 = $ 0.02
Let’s substitute:
Ф = N * Ф1;
Ф = N * B * S;
Ф = 230 * 0.98 * 0.02;
F = 4.5 Wb.
Answer: Ф = 4.5 Wb.
