Note on magnetic field

Webis called the magnetic field B. (Note that in some texts, the term magnetic field is reserved for the quantity H,andB is called the magnetic induction.) In terms of the field, the magnetic force on i dl is Equation (3.5) involves the vector cross product. The force is perpendicular to both the current element and magnetic field vector.

WebThe magnetic field is related to the current as follows. Assume that dl is an element of length (pointing in the direction of current flow) of a filamentary wire that carries a current I and r is the coordinate vector from the element of length to an observation point P, as shown in Fig. 5.4. Then the magnetic field dB at the point P is given ... http://www.phys.ufl.edu/~acosta/phy2061/lectures/MagneticField.pdf minecraft education edition android https://maertz.net

Webmagnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges.

Early in the nineteenth century, people discovered that electrical currents cause magnetic effects. The first significant observation was by the Danish scientist Hans Christian Oersted (1777–1851), who found that a compass needle was deflected by a current-carrying wire.
