"success!" "success!" "Ha ha ..." There were bursts of laughter and cheers from my home. This is an interesting experiment that my partner and I are doing.

At school, teachers often do many interesting experiments in science and technology interest classes, which aroused my strong interest. So, on Sunday, I invited several close friends and said mysteriously, "Shall we do an experiment?" I heard that I was going to do an experiment, and my neighbor's little brother was attracted.

The partners asked noisily, "What experiment?" "What is it?" I magically took out a candle, a magnet and an iron bar. Guys, I don't know what I'm selling.

Yao medicine, I got two monks confused. I lit the candle with confidence, stood on the table, sucked the magnet with an iron bar and took it to the fire to burn. At first, the magnet was tightly attached to the iron bar. The flame of the candle greedily licked the magnet. After a while, the magnet, like a sick person, weakly stuck to the iron bar and was about to fall off. Finally, bang, the magnet fell to the ground. "The experiment was a success! Success! " Everyone is dancing, so don't mention the joy.

Why do magnets lose their magnetism when heated? Everyone can't help but ask a question mark in their hearts and go to books to find the answer. It suddenly occurred to me that there was something about introducing scientific knowledge in Youth Science Illustrated, so I went to see Youth Science Illustrated. "I found it!" I cried in surprise, as happy as Columbus discovered the new continent.

It turns out that magnetism and electrons are inseparable, and there is magnetism around the moving electrons. This is called electromagnetic effect. Electromagnet is red-hot, and the molecules in it are so hot that they run around, which destroys the consistency of electron movement direction and the magnetic effects cancel each other out, so the whole "magnet" no longer shows magnetism. I think: in household appliances, there is a magnet on the radio speaker, so you can't let high-temperature objects get close. As you can imagine, there are speakers and magnets on the TV. Isn't the principle the same? If a hot object is close to the magnetic refrigerator, won't the refrigerator be damaged? No wonder the instructions emphasize not to approach high-temperature objects. I told everyone what I thought, and they suddenly understood. The neighbor's little brother seemed puzzled, frowned and said solemnly, "I seem to understand, but I don't seem to understand." A word made us laugh.
