Web72.03 -- EMF induced by moving magnet. A wire coil is connected to a galvanometer. When you push a magnet towards the center of the coil, then pull it away, the galvanometer needle deflects in one direction, then the other. How far the needle deflects depends on the strength of the magnet and how fast you move it. Web14 de mai. de 2024 · Artwork: An ammeter (A) is a sensitive instrument that measures only relatively small currents. If you want to measure bigger currents, you need to divert a high proportion of them around a "shunt" resistor (Ω). Since the meter and the shunt are in parallel, they have the same voltage across them. churches smoked chicken meal
