WebThus the rate of change of the magnetic flux is. Δ Φ Δ t = Δ ( B A cos θ) Δ t = B Δ A Δ t = B v ℓ, 20.34. where we have used the fact that the angle θ between the area vector and the magnetic field is 0°. Once we know the emf, we can find the current by using Ohm’s law. Web15 de jun. de 2024 · What you need to know is that the induced e.m.f. is proportional to the rate of change of magnetic flux: $$\varepsilon = \frac{d\phi}{dt}.$$ Intuitively, this rate is going to be the largest when the magnet is entering the coil and when it is leaving the coil. That is because before entering the coil, the flux through the solenoid is almost negligible …
