31 sie 2017 · This document discusses magnetic fields and their properties. It explains that magnets have two poles, north and south, and that like poles repel while unlike poles attract. It defines magnetic fields as representing magnetic forces that act at a distance without physical contact.
15 sie 2013 · It defines magnetic fields as representing magnetic forces that act at a distance without physical contact. It describes magnetic field lines and their properties, including that their direction shows the field orientation and strength increases with closer spacing.
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.
Magnets are used in various technologies like electromagnets, motors, and magnetic storage devices. 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.
A moving charge or current creates a magnetic field in the surrounding space (in addition to E). The magnetic field exerts a force F. on any other moving charge or current present in that field. The magnetic field is a vector field each point in space.
16 wrz 2014 · Understanding Magnetism SECTION24.1 Magnetic Fields Around Magnets (cont.) • Magnetic field lines are used to help us visualize a field, and they also provide a measure of the strength of the magnetic field. • The number of magnetic field lines passing through a surface is called the magnetic flux.
