Magnetic flux describes the lines of a magnetic field emanating from, and in the region of space surrounding, a magnetized object. Quantitatively, magnetic flux describes the magnetic field lines of force that traverse a given cross-sectional area.

Magnetic fields exert forces on moving charged electrical particles. In this regard magnetic field lines are lines of force along which moving charged particles will be deflected. Magnetic fields are represented by continuous magnetic flux lines thatare depicted to emerge from north-seeking magnetic poles and enter south-seeking magnetic poles.

Magnetic fields are characterized by magnetic flux density with the density of magnetic flux lines directly related to the magnitude of the magnetic field. The greater the magnitude of the field (field potential) the more dense the magnetic flux lines. At magnetic poles the magnitude of the magnetic field strength is at a maximum and the magnetic field lines are...
