Space-saving solution due to short demagnetization coils

During the testing of defects in ferromagnetic materials using the eddy current or flux leakage method, the test material is generally magnetized until saturated. After the test, the material contains residual magnetization which has to be reduced to the specified values prior to delivery. FOERSTER provides the high-performance EMAG demagnetization unit for this purpose. thanks to its short coils, it is space-saving and can be integrated in your testing line.


  • Reduces the magnetic residual field strength below specified limit values for approval and supply specifications for semi-finished products
  • Short demagnetization coils facilitate space saving integration in the testing line
  • Test material diameter up to 240 mm
  • Two demagnetization coils installed successively can be operated for increasing material throughput
