Devices that applies the principles of electro-magnetic induction –
(a) Generators [transfers mechanical energy to electrical energy through magnetic
energy]
(b) Motors [transfers electrical energy to mechanical energy through magnetic
energy]
(c) Transformers [ transfers electrical energy to electrical energy trough magnetic
energy

Magnetic Fields
Magnetic Flux : (Symbol ϕ, Unit: 𝑤𝑒𝑏𝑒𝑟 or Wb) Magnetic flux lines do not have
origins or terminating points as do
electric flux lines but exist in
continuous loops.
The magnetic flux lines radiate
from the north pole to the south
pole, returning to the north pole
through the metallic bar.
There exists an equal spacing
between the flux lines within the
Fig. Flux Distribution for a permanent magnet
core and a symmetric distribution
outside homogeneous magnetic
Flux === ====== ======= current in
materials.
in magnetic circuit electrical circuit
The strength of a magnetic field in a particular region is directly related to the
density of flux lines in that region. The magnetic field strength at a is twice that at b.
