How electromagnetic induction is used in transcranial magnetic simulation?
Your classmates have different opinions about why electricity is generated in the generator. Annie claims it’s the movement of the magnets that generate energy, since that’s a form of kinetic energy. Josue claim’s the electricity is generated by the power of the magnets on the outside of the moving center. Which analysis correctly describes how the electricity is generated? (a) The movement of the wire within and the magnets are needed in order for an electrical current to be generated (b) The movement of the center is what generates the electricity, the magnets on the outside don’t need to be there at all (c) The electrical current would be generated if the magnets were incredibly strong and the middle piece did not rotate (d) The placement of magnets on the outside is more important than the movement of the center for the generation of electricity
