Magnetic materials

Terms  Associated  with  Magnetic  Materials

 

Magnetic  field. The  space  around  a magnet  or a current  carrying  conductor  within  which  its magnetic  effects  can be observed  is called  the magnetic  field  

Field  strength  . The magneto motive  force  per metre  length  of the magnetic  circuit  ( which  is homogeneous  and  of uniform   cross  sectional area) is called  magnetic  field strength  or field  intensity  . It is  represented  by symbol "H" .If the mean length  of the magnetic  circuit is "l" metres then 

Flux  or linear of force. The total magnetic  lines  of flux  passing  through the  material  is called  magnetic  flux   .Its symbol is phi and unit of measurement  is weber  
1 Weber =10^8lines=10^8Maxwell 

Magnetic  circuit  it is a path  of magnetic  flux  forming a closed  circuit  .

Magnetic  force     It is the force  exerted by one magnet on another  either  to attract it or to repel it
