1.	One of the methods used to demagnetize a specimen involves keeping the specimen in the coil and slowly decrease the current to ____________(a) double the initial value(b) 0(c) 26.5(d) highThe question was posed to me by my college professor while I was bunking the class.My query is from Testing Aircraft Materials topic in division Testing Aircraft Materials of Aerospace Materials & Processes
Answer» Right CHOICE is (b) 0 Best explanation: Demagnetization is done on materials that have been SUBJECTED to the magnaflux inspection method. There are two METHODS to do it, and one of them is keeping the specimen in the coil and SLOWLY decreasing the CURRENT to zero.
