MAGNETISATION AND MAGNETIC INTENSITY

     MAGNETISATION AND MAGNETIC INTENSITY

 MAGNETIC INTENSITY [H]

IT IS THE PROPERTY OF AN EXTERNAL MAGNETIC FIELD UP TO WHICH IT CAN MAGNETISE THE SUBSTANCE KEPT INSIDE IT BY ALLIED THE DOMAINS PRESENT IN THE SUBSTANCE.

                                                       H = Bo/μo

IT CAN ALSO BE DEFINED AS THE RATIO OF THE MAGNETIC FIELD IN A VACUUM TO THE ABSOLUTE PERMEABILITY OF FREE SPACE.

INTENSITY OF MAGNETISM [I]

IT IS A PROPERTY OF SUBSTANCES UP TO WHICH THEY CAN MAGNETISE THEMSELVES WHEN KEPT INSIDE THE EXTERNAL MAGNETIC FIELD. 

                                                

                                                        I = M/V

THE INTENSITY OF MAGNETISM IS DEFINED AS THE RATIO OF MAGNETIC DIPOLE TO THE VOLUME.

                                                      I = NIA/V

MAGNETIC SUSCEPTIBILITY [Xm]

IT IS A PROPERTY OF SUBSTANCES HOW FAST THEY CAN MAGNETISE THEMSELVES WHEN KEPT INSIDE THE EXTERNAL FIELD.

                                                     

                                                     Xm = I/H

IT IS THE RATIO OF INTENSITY OF MAGNETISATION TO THE MAGNETIC INDUCTION.

MAGNETIC INDUCTION [MAGNETIC FIELD]

MAGNETIC FIELD IS DEFINED AS THE FORCE EXPERIENCED BY THE UNIT POSITIVE CHARGE. WHEN IT IS MOVING WITH A VELOCITY OF 1M/S AT THE ANGLE OF 90 DEGREES INSIDE IT.

                                   B =  μo [H+I]   OR  B = F/qvsinθ

MAGNETIC PERMEABILITY

IT IS THE PROPERTY OF THE MEDIUM THROUGH WHICH THE FIELD LINES PASS BETWEEN THE SOURCE AND THE SUBSTANCE.

                                               

                                              μo = B/H

 

IT IS DEFINED AS THE RATIO OF MAGNETIC FIELD TO MAGNETIC INTENSITY.
