22.1: Magnetic Flux, Induction, and Faraday’s Law

WebJul 7, 2024 · Electromagnetic induction (also known as Faraday's law of electromagnetic induction or just induction, but not to be confused with inductive reasoning), is a process where a conductor placed in a changing magnetic field (or a conductor moving through a stationary magnetic field) causes the production of a voltage across the conductor. This … WebWe have a loop of wire and a bar magnet. In one experiment, we move the magnet towards the loop of wire. The flux through the loop increases. The loop now has a current, meaning there is an electric field pointing around the loop. This is induced EMF. Induced EMF is calculated using the change in flux through a stationary loop. WebThe dangers of EMF radiation are related to strength of radiation and length of exposure. While actual EMF radiation levels will vary between manufacturers, and even between models, it’s fair to say that induction cooktops pump out reasonably high levels of EMF radiation.
