How a magnet is made
WebMagnet Manufacturing Process. There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, … 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.
