WebMay 8, 2000 · In an electromagnet, there is a coil of wire around an iron bar (the armature). When you apply current to the electromagnet's coil (with a battery, for instance), the coil creates a magnetic field in the armature. In a generator, you reverse the process: You move a magnet past the armature to create electric current in the coil. WebThe polarity of the magnetic field is perpendicular to the coil of wire. Each time the current changes direction, the polarity of the magnetic field changes. This means that if the coil of wire is parallel to the ground, the magnetic field is constantly pushing down into the ground and then pulling back out of it.

WebSo does the bulb light up when there's a changing magnetic field because: a moving electromagnetic field will exert a force on the free electrons of a wire to move; moving electrons is the definition of current; thus the bulb lights up. The force applied depends on the direction of the changing magnetic field, thus changing the way current flows. WebAnswers for Coil of wire around an iron core crossword clue, 8 letters.
