15 sie 2013 · The document discusses how electromagnetic induction works to generate electricity using magnets and coils of wire. It explains that changing magnetic fields can induce currents in conductors and that this principle is used in electrical generators.
29 kwi 2012 · 6.3 - Magnetic Force and Field. 1. Every magnet has two poles, north and south, and magnetic fields are described by field lines that run from the north to the south pole. 2. A current-carrying wire in a magnetic field experiences a force perpendicular to both the current and the magnetic field.
along the direction of the magnetic field produced by the magnet, as depicted in Figure 8.1.1. Figure 8.1.1 Magnetic field produced by a bar magnet Notice that the bar magnet consists of two poles, which are designated as the north (N) and the south (S). Magnetic fields are strongest at the poles. The magnetic field lines
The strength of a magnetic field decreases with distance from the magnet. Ferromagnetic materials can be magnetized by an external magnetic field and retain magnetism. Magnets have two poles, north and south, and magnetic forces exist between them.
The document describes magnetic fields and forces. It defines key terms like magnetism, magnetic domains, magnetic poles, and magnetic field lines. It explains how unlike magnetic poles attract and like poles repel each other.
31 paź 2014 · Magnetic Fields • ALL magnets produce a magnetic field • Strength of magnetic field depends on: • Material magnet made from • How much object is magnetized • How far from magnet. • Magnetic field lines used to represent magnetic field • Like electric field lines represent electric field
