How a magnetic field acts
WebHuman magnetism is a popular name for an alleged ability of some people to attract objects to their skin.People alleged to have such an ability are often called human magnets.Although metal objects are the most … 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.
