Magnetic field

A magnetic field is the magnetic effect o electric currents an magnetic materials. The magnetic field at ony gien pynt is specified bi baith a direction an a magnitude (or strenth); as such it is a vector field.[nb 1]

Magnetic field o an ideal cylindrical magnet wi its axis of symmetry inside the image plane. The magnetic field is represented bi magnetic field lines, which show the direction o the field at different pynts.


  1. Strictly speakin, a magnetic field is a pseudo vector; pseudo-vectors, which an aa include torque an rotational velocity, are seemilar tae vectors except that thay remain unchynged when the coordinates are invertit.
