Materials with 'hard' magnetic B/H characteristics often show a strong residual magnetism. This makes them suitable for making permanent magnets. If the ring material were magnetised, then the magnetised material itself will create a flux in the ring. No current carrying coil will be required.
For a permanent magnet, flux is produced by the alignment of magnetised domains within the material itself. (c.f earlier notes relating to residual magnetism in B/H curve). In this case, the flux exists without the need for a coil, i.e. N.I = 0. Hence applying Ampere's Law results in:
Hence eqn 1 and the B/H curve must be simultaneously satisfied and to give the flux density and magnetic field strength in the magnetic material (and hence also the air gap)
from equation (1) Bc/Hc=-Lc/Lgµ0
which is slope of a straight line. The flux density and magnetic field in the magnetic circuit is given by the point at which eqn (1) cuts the B/H curve. Permanent magnets are widely used in transducers:- loud speakers, measuring meters, D.C. motors etc.
AC Link Chopper This copper has two stage conversion. First DC is converted into AC by the use of inverter. The magnitude of AC voltage is varied by the transformer and
Consider the circuit shown in Figure in the t -domain as well as in the s-domain. Formulate the s-domain nodal equations and use MATLAB to solve for V A (s) and V B (s).
In practice, it is usually better to wind the field coils on the rotor and supply the field current to them via slip rings. As the rotor turns, the changing magnetic field expe
Describe the uses of GPS map This is far safer because a driver of a vehicle doesn't have to consult maps while driving. It also removes error (for example going the wrong way
