A square frame with a side of 3 cm is in a uniform magnetic field with an induction of 0.05 T. The plane of the frame is perpendicular to the lines of induction. The frame is rotated 90 degrees around one side. Determine the change in the magnetic flux penetrating the frame. You will receive the answer in microWb.
To solve the problem, you need to use a formula of the following type:
Ф = B * S * cos a;
Substitute the values into the formula above:
F = 0.05 * 3.14 * 9 * 10-4;
We get the following:
F = 141 μWb;
Let’s translate into the values we need:
Ф = 0.1 mVB.
Answer: Ф = 0.1 mVB.
