Do you know about the protection by means of screens. It seems easier to attenuate - if not eliminate - the magnetic field in which the watch is located. For this purpose, a screen is used, that is to say a body which attracts the lines of force so that in the screen itself the magnetic field is more intense while it is reduced outside the 'screen. If the watch is in a screen box, the lines of force will pass into the box and the movement of the watch will be preserved. Totally? or in part? The screen must be made of a material which strongly attracts the lines of force; this property, permeability, is expressed by a number, u indicating the relationship between the intensity of the field in the body and that of the field when the body is replaced by air. Substances with high permeability are: soft iron as pure as possible, for example rafiqsonsonline(.)com/product-category/omax-watches/ electrolytic iron, Armco iron; alloys called mumétal, permalloy, which contain iron and nickel with additions (copper, chromium, molybdenum).
