What is Magnetic current? |
| Answer» The term "magnetic effects\xa0of\xa0current\xa0" means that " a\xa0current\xa0flowing in a wire produces a\xa0magnetic\xa0field round it ". the\xa0magnetic effect\xa0of\xa0current\xa0was discovered by Oersted found that a wire carrying a\xa0current\xa0was able to deflect a\xa0magnetic\xa0needle.\xa0Moving\xa0magnetic\xa0fields pull and push electrons. Metals such as copper and aluminum have electrons that are loosely held. Moving a\xa0magnet\xa0around a coil of wire, or moving a coil of wire around a\xa0magnet, pushes the electrons in the wire and creates an electrical\xa0current. | |
