WebWhat are the three ways in which voltage can be induced in a loop of wire? Move a magnet near the loop, move the loop near a magnet, change current in a nearby loop. How does the frequency of induced voltage relate to how frequently one pole of a magnet is plunged in and out of a coil of wire? The frequencies are the same. WebQuestion: Five loops are formed of copper wire of the same gauge (cross-sectional area). Loops 1-4 are identical; Loop 5 has the same height as others but is longer. At the instant shown, all the loops are moving at the same speed in the directions indicated. There is a …
