How does cutlery get magnetised

This is because as you add more thermal energy to the material, the atoms are able to move about more randomly, says Sahajwalla, destroying the kind of order they had previously. The reverse is also true: it's possible to induce magnetism in some non-magnetic materials by working them at relatively low temperatures. Tags: steel , chemistry , engineering.

Cutlery Magnet In addition to automating your processes, a cutlery magnet contributes significantly to hygiene and ergonomics, since cutlery no longer has to be processed manually.

Improve hygiene and ergonomics Cutlery magnets are designed to extract cutlery automatically from the trays. The salts and minerals that come from the water line and your pipes could adversely influence the taste of the coffee," she says, plus they can clog up the coffee maker over time. Ravi Deshpande of Toronto adds that water contains dissolved oxygen and that water with more oxygen, and drinks made from it, taste better. That's because the hot water probably sat in the water heater for some time, allowing a longer period to lose its dissolved oxygen.

Marit of Oakville, Ont. Why not use red signals instead? There are not many things within a kitchen that I can imagine might have a strong enough magnetic field to magnetise a knife.

The fact that it is magnetised at the tip would lead to to suspect that the tip may have got very hot at some time, and this may have made it more susceptible to magnetisation. The only practical purpose I can imagine for a strong magnetic field in a kitchen might be for some sort of magnetic clamp.

If my memory does not fail me in this, if an object is magnetized by contact with a magnet, the magnetism will be strongest at the tips, even if the contact with the permanent magnet was on another place. You can also magnetize in an electromagnetic field, but contact with a permanent magnet is much easier by far, and even then magnetism will be stronger at the tips.

What was weird was that the knife was of the same design as any other knife in the resturant, but is the only one that was magnetic. The knife wasn't really for throwing It was a small meat cutting knife, nothing resembling a dagger or anything of the sort.
