Dear all,
I need a suggestion for my work. I have to measure the variation of some optical features of a material in presence and absence of a magnetic field. Hence, I need to “switch on” the magnetic field in a given instant time, to record the signal an then ““switch off”, or even to change the direction of the magnetic field. Moreover, I need that this “object” is small and handy.
Do you have any suggestions, a part a small permanent magnet? Probably the solution is banal, but at the moment I am not able to find it.
Thanks a lot
