Web11 jan. 2024 · What is electromagnetic induction? If you attached a metal wire to a battery, you would create a current – electrons would move along the wire. Then, if you put this wire in a magnetic field, an additional electric force would be induced by the motion of electrons in the field. WebPHY2049: Chapter 30 21 Induced currents ÎA circular loop in the plane of the paper lies in a 3.0 T magnetic field pointing into the paper. The loop’s diameter changes from 100 cm to 60 cm in 0.5 s What is the magnitude of the average induced emf? What is the direction of the induced current? If the coil resistance is 0.05Ω, what is the average induced current?
