The main considerations circuit design, magnetic flux density of air gap
uniformity at the end of operating conditions the effects of demagnetization and
environmental factors.
magnetic circuits, you must understand the system
requirements on the magnetic properties of priorities, good
identifying the characteristics of magnets
.
In general, the density of the air gap Bg is the most important, it can
be demonstrated by the current analysis, for the

Line demagnetization factor, the magnetic force is proportional to withdraw
magnetic system, the work can have. Environmental factors affecting
The total flux available
, Also establishes the demagnetization factor.
If several materials are consistent with the requirements of design, the product
design elements as possible. To understand this,
We remember how the product can be calculated. This is the maximum energy
product can be reduced, with a strong Siaosite Siu said that
Conditions can also be explained entirely the product of calculation. calculated curves

The standard curve of magnetic materials can be obtained from external
energy unit, the device can be used for energy is one of the
The use of magnets. Standard curve with equation Bi = B "I" directly
related to the energy curves. Standard curve and cross

Item of the residual magnetic flux density Br, points of intersection with

Performance. For modern "lines" high-energy materials at room temperature
The value of the father is somewhat higher than the value of HC, so that B / H and
Ur is the permeability of the performance slightly above 1. Thus
The requirement to be inaccurate, we can consider the B / H and whether a product can be
simplified
