Magnetic Measurement of Single Strip

The standard Epstein frame method to evaluate magnetic properties of electrical steel sheet requires approx. 20 strips for testing, which shall be nun of use after testing. Single strip test method requires only one strip of dimension 30x305mm for testing. (Epstein test method gives average result of 20 strips and single strip method gives result of only one strip so there might be little difference in the result comparing to Epstein test method)
