Check out the refrigerator door

Progress isn’t always for the better.

For example, those newfangled stainless steel refrigerator doors don’t hold magnets. And that means you can’t post those class pictures, favorite comics and the test your daughter got an A+ on, among other heartwarming life events.

Well, the Journal-World has the next best thing: The Refrigerator Door, a page of events worthy of placing on your own refrigerator.

The feature will appear on Tuesdays starting today.

We hope to get all of your submissions published in the Journal-World. But if we can’t, they will be posted online at www2.ljworld.com/refrigerator/.

To submit news from your special occasion, go to www2.ljworld.com/contribute/refrigerator_door/

if your stainless steel refrigerator doesn't hold magnets then it's probably brushed aluminum...

Sorry, AreUNorml, since I'm not normal I can answer this as an engineer would:

Stainless steel is iron and carbon which makes steel. It becomes stainless steel when you add chrome......about 8% to 18%.

This is probably magnetic and probably only available in the home as knives.

Add some nickel and you get a much more malleable and ductile (non-brittle) metal. This is what you want for a fridge and just about everything else around the house and garden, etc.

But the nickel kills the magnetic properties of the iron by changing the crystalline structure of the solid. Magnetism requires "domains" for swirling charge to make a magnetic field. These domains are tiny crystalline regions that are regular and lined up and support the magnetic field.

Nickel destroys this structure in SS.

No reefer-magnets. Sorry.

I love this idea! Putting things on the fridge been a part of my life for as long as I remember! Which is why I chose to purchase a white fridge... one it will never go out of style and two it's magnetic. :)
