What is the induction of the magnetic field in which the conductive circuit with an area of 80 cm square is placed? The magnetic flux penetrating the circuit is equal to 0.4 mWb

To determine the magnitude of the magnetic field, we will use the formula: Ф = B * S, from where we express: B = Ф / S.

Variables: Ф – magnetic flux in the circuit (Ф = 0.4 mVb = 0.4 * 10-3 Wb); S is the area of the considered conductive circuit (S = 80 cm2 = 80 * 10-4 m2).

Calculation: B = F / S = 0.4 * 10-3 / (80 * 10-4) = 0.05 T (50 mT).

Answer: The induction of the magnetic field, according to the calculation, is 50 mT.
