Formula for emf induced

WebAny change in magnetic flux Φ induces an emf. This process is defined to be electromagnetic induction. Units of magnetic flux Φ are T ⋅ m 2. As seen in Figure 4, B cos θ = B⊥, which is the component of B perpendicular to the area A. Thus magnetic flux is Φ = B⊥A, the product of the area and the component of the magnetic field ... WebThe SI unit for mutual inductance M is called the henry (H) in honor of Joseph Henry (1799–1878), an American scientist who discovered induced emf independently of Faraday. Thus, we have 1 H = 1 V · s/A. From Equation 14.1 and Equation 14.2, we can show that M 21 = M 12, so we usually drop the subscripts associated with mutual inductance and ...
