What side of the microwave does the refrigerator magnet go on?
Finally, some anecdotal evidence: our own microwave oven has a series of “fridge magnets” stuck to its right side - the side closest to the magnetron and control electronics. They have been there for 7 years, and our microwave oven continues to operate normally.
Where is the microwave antenna?
The microwaves are actually emitted by the metal cap at the top of the photo, which acts as an antenna. That cap is usually mounted closest to the oven’s cooking cavity, just behind an insulating cover.
Why is my microwave not working?
If your magnet is metal it causes the microwave energy to be reflected back into the emitter (voltage standing waves) and can quickly overheat and kill it .
What happens when you put a magnet on a metal surface?
When you place a magnet on an iron or steel surface, most of the magnetic field on that side of the magnet remains within the steel (which is much more magnetically permeable than air), and little of the magnetic field gets through to the other side of the microwave’s outside shell.
How does a microwave heat water?
PS: the way microwaves heat water is through conservation of momentum; in general, the water molecule absorbs the light and begins to spin, increasing the kinetic energy of the material. As the molecules bounce around, the water heats up the other molecules which don’t get as excited by the microwaves. Food heats from the outside in while in a microwave oven, and the reason is that the water closer to the surface has plenty of access to the microwaves, getting “their fair share”, but the microwaves are still absorbed by other molecules (they just don’t spin as much), causing the water molecules closer to the center to get depressingly less radiation. The explanation I gave above concerninc ice vs water in a microwave is also the reason why frozen food takes so long to thaw in a microwave. You’re better off giving the food a nice, hot, bath than shoving it into a microwave.
Why is microwave energy important?
Because all microwave energy is at wavelengths of only a few inches. And size is a critical factor in the travel of all RF energy. Smaller sizes can absorb huge amounts of energy. Especially if it’s got water molecules in it - like food. It’s a matter of geometries, resonances and size.
Why can't you put metal in a microwave?
There are two reasons not to put metal stuff in the microwave: the first one is exactly the reason the microwave is made of metal too, namely, metal will reflect the microwaves. So say you used a metal tray, for example. Now anything near the metal will not receive microwaves and the cooking will be uneven.
