What happens if you put metal in the microwave?

Of course it will! But it's a long time! In a short time, there will be a spark! Be careful!

If the plane is destroyed, people may die, so be careful.

When the microwave oven heats up metal utensils, electric sparks will be generated with the microwave and the microwaves will be reflected, which will damage the furnace and prevent the food from being heated. If a metal object is heated in the microwave for a long time, sparks are likely to erupt. Sparks occur frequently and may ablate metal walls, and microwaves cannot be generated normally.

It can also cause the microwave oven to malfunction and reduce the life of the microwave oven. The metal itself is not the cause of the spark, but the shape of the metal is the culprit. Metals with sharper edges are more likely to attract flowers, while objects with rounded edges are relatively safer.

The microwave oven is heated by microwaves, which can be absorbed by water-containing proteins and fatty substances, and the electromagnetic energy is converted into heat energy. There are two kinds of substances in the heating object: whether there is (have) polar molecule dielectric. Polar molecules are arranged in an orderly manner along the magnetic field in the magnetic field, the direction of the magnetic field changes, the order changes, and a large number of molecular movements convert kinetic energy into heat energy.

If the food is heated in a metal container, the temperature of the food in the container will not rise even if it is burned for an hour, because the microwave will reflect all the food back immediately after encountering the metal container, and the food will not be heated by a heat source. The more dangerous thing is still to come, because the high-frequency microwave is all reflected back, which forms a "high-frequency short circuit" in electronic technology, which will cause the electron tube anode emitting microwaves to produce high temperatures, burn to redness and damage.

The food containers used in the microwave are very picky. Generally, ceramic or special plastic can be used. And not metal or enamel. This is because microwaves will "short circuit" and reflect when they come into contact with metal products.

A microwave oven is a cooking appliance that uses food to absorb microwave energy in the microwave field to heat itself. The microwave generated by the microwave generator in the microwave oven establishes a microwave electric field in the microwave oven cavity, and takes certain measures to make this microwave electric field distributed as evenly as possible in the furnace cavity, puts the food into the microwave electric field, and controls its cooking time and microwave electric field intensity by the control center to carry out various cooking processes.

Generally speaking, microwave is a high-frequency electromagnetic wave, which itself does not produce heat, there are microwaves everywhere in the universe and nature, but there are microwaves in nature, because they are not dispersed, so they cannot heat food.

When the microwave is absorbed by the food, the polar molecules in the food (such as water, fat, protein, sugar, etc.) are attracted to oscillate rapidly at a speed of 2.45 billion times per second, and the macroscopic manifestation of this is that the food is heated.

The principle of microwave heating is simply put: when microwaves are radiated to food, food always contains a certain amount of water, and water is composed of polar molecules (the positive and negative charge centers of molecules, which do not coincide even in the absence of an external electric field), and the orientation of this polar molecule will change with the microwave field. Due to this movement of polar molecules of water in food.

and the interaction between adjacent molecules, which creates a friction-like phenomenon that increases the temperature of the water and, therefore, the temperature of the food.

When food is heated in the microwave, the inside is also heated at the same time, so that the whole object is heated evenly and heats up quickly. It heats up to 5cm deep into food at a frequency of 100 million times per second, accelerating the movement of molecules.

The metal and the microwave will refract, which can cause sparks, which can damage the microwave oven in the light case and occur in the heavy case**. Metals are dangerous under the microwave, and metals and metal edges cannot be used.

If a metal object is left in the microwave for a long time, sparks are likely to erupt. This is because when a microwave hits a metal, the electrons in the metal collide with other electrons to produce a high-density negative charge point, and the excessive voltage drives the electrons to move towards the lower voltage part, which may cause sparks.

1. Metal cannot be heated in the microwave.

2. Metals carry a large number of free electrons and are good conductors of electricity. When a metal object is heated in a microwave oven, the free electrons in the metal will move back and forth, so the microwaves will be reflected and cannot enter the container to heat the food.

3. In addition, if a metal object is heated in the microwave for a long time, sparks may occur. This is because when microwaves hit metal, the electrons in the metal collide with other electrons to produce a high density of negative charge points, and the excessive voltage drives the electrons to move towards the lower voltage part, resulting in sparks.
