Most metal detector have 2 coils – one coil carries alternating current usually at very high frequency (1-10 KHz) and other coil acts like a receiver. The excited coil generates a magnetic field and this induces a small amount of current in the receiver coil. This current (also called as Induced current or Eddy current) is known and calibrated. Now when you take this arrangement near a metallic (or ferromagnetic) substance, two things happen. First, the excited coil also induces an eddy current in the metallic (or ferromagnetic) substance. This eddy current produces its own magnetic field that opposes the magnetic field produced by the coils. This causes the eddy current in the receiver coil to drop. A sensor senses this drop in eddy current from the expected value and gives a signal indicating the presence of a metallic substance. !

EMS for SOLIDWORKS is the first and only completely embedded Gold Certified software for SOLIDWORKS which helps SOLIDWORKS users study their magnetic, electric and electromagnetic designs seamlessly. It can utilize the geometry created using SOLIDWORKS directly for simulation. Its user interface emulates SOLIDWORKS and hence there is no learning curve associated with the EMS software for SOLIDWORKS users 5 N9 s3 h( E: N% A!

EMS for SOLIDWORKS helps bearing designers to size their magnetic arrays to support various designs of the shaft (basically different weights). This way the bearing can ensure optimum performance. Another advantage of a magnetic bearing is that it can support offset of the inner cylindrical array wrt to the stationary outer cylinder.0 `4 V- A3 B- x

The N-S directions of each magnet is indicated by the black arrows. This type of arrangement can be easily created in EMS and the magnetic flux distribution and the axial force acting on the inner array can be visualized and computed respectively.5 G3 @3 J4 R0 t5 e# @6 D9 g$ }+ ]8 b
Variation of axial force acting on the inner magnet array with the offset is shown below and is automatically computed by EMS. Note that as the offset increases, so does the axial force but after a point the force reduces. * d/ s8 a, Z0 @1 H[attach]383942[/attach] % b.
