So NASA’s scientists wrapped the cables in a whole lot of aluminum foil and found that in 1979 Voyager 1 had safely swung past Jupiter and would continue on its legendary journey. Show comments ...
Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
Aluminium foil (or aluminum foil in American English; occasionally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
Indeed, some shoplifters use clothes lined with aluminum foil. Low-frequency magnetic systems will require more shielding than radio-frequency systems due to their use of near-field magnetic coupling. Magnetic shielding, with steel or mu-metal, would be more effective, but also cumbersome and expensive.
For static or slowly varying magnetic fields (below about 100 kHz) the Faraday shielding described above is ineffective. In these cases shields made of high magnetic permeability metal alloys can be used, such as sheets of permalloy and mu-metal [9] [10] or with nanocrystalline grain structure ferromagnetic metal coatings.

Cooking surface manufacturers prohibit the use of aluminum foil in contact with an induction cooking surface. Cookware must be compatible with induction heating; generally, only ferrous metal can be heated. Cookware should have a flat bottom since the magnetic field strength (heating power) drops rapidly with distance from the surface.
