Magnetic induction intensity magnetic induction
Description of the magnetic field strength and direction of the basic physical quantities. Vector is commonly used symbols B said.
In physics use the strength of the magnetic field strength magnetic flu (also called magnetic induction), magnetic induction of the magnetic sense that strong magnetic induction of small, weak sense of magnetic said. This is called magnetic induction physical strength, but not called magnetic field strength is the result of the history of magnetic field strength that the term has been used by other physical quantities.
point charge to speed v in a magnetic field by the movement of f role. In the field to the conditions, the size and charge f the direction of the movement. When v along with a special direction or reverse, the force is zero; v When this special force perpendicular to the direction of the largest, fm. Fm and | q | v and proportional to the ratio of charge has nothing to do with the campaign, reflecting the nature of the magnetic field, the magnetic field intensity is defined as the size, that is. B direction is defined as: the most suffered by the positive charge vigorously fm charge to the direction of movement direction v, spiral right way forward. Definition of a B after moving charge in the magnetic field B at which the force could form to f = qv กม B, namely, the Lorentz force equation.
