Note on magnetic field
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 ... WebA magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.: ch13 : 278 A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and …
