# What is the magnetic flux of a uniform magnetic field created by an electromagnet if the induction

What is the magnetic flux of a uniform magnetic field created by an electromagnet if the induction of the magnetic field is 0.5 T and the cross-sectional area of the electromagnet is 100 cm2?

To determine the magnitude of the magnetic flux created by the used electromagnet, we apply the formula: Ф = B * S.

Variables: B – magnetic induction in the electromagnet (B = 0.5 T); S is the cross-sectional area of the considered electromagnet (S = 100 cm2 = 0.01 m2).

Calculation: Ф = B * S = 0.5 * 0.01 = 5 * 10-3 Vb = 5 mVb.

Answer: The magnetic flux created by the used electromagnet is 5 mWb.
