How do anti-gravity frogs float?

Science is mysterious, so many scientists want to discover the secret of science, and human beings are constantly creating science and transforming society with science, so our society will develop so fast. In fact, science will shock people. As early as 1977, scientists made anti-gravity frogs. To many people's surprise, how did this frog float? In fact, the reason is very simple, because this frog was placed in a 32 mm spiral tube and was affected by magnetic force.

We all know that magnets are magnetic, but their magnetic force is relatively small. In this experiment, the anti-gravity frog was placed in a magnetic field 654.38+0.6 million times larger than that of a magnet.

In fact, not only frogs can be suspended, but also objects such as water droplets can be suspended here without shaking.

In this experiment, scientists also summed up a rule, that is, using the diamagnetism of objects. There are three kinds of diamagnetism, namely ferromagnetism, paramagnetism and diamagnetism.

The most obvious representative of ferromagnetism is iron. The atoms in the internal orbit of iron are evenly distributed, and the number of electrons is equal, but in opposite directions, so there is no magnetic field inside. The number of external electrons in iron is the cardinal number, which cannot be offset, so there will be a weak magnetic field. Many of us have played with magnets, that is, whether it is near the iron south pole or the north pole, it will show a certain force. Same sex will repel each other when they are together, and opposite sex will attract each other when they are together.

The most representative materials of paramagnetism are aluminum and thin, but paramagnetism is difficult to find because of its small magnetic force. But it can still be detected by certain means.

Diamagnetism is very common. Materials such as paper and sawdust are diamagnetic. Because the external electrons of these materials are paired and have no magnetism, even if an external magnetic field is applied, there will be no reaction.

So how does a strong magnetic field suspend diamagnetic substances? In fact, the reason is very simple, that is, scientists have discovered electromagnetic induction. When a closed magnetic field is generated around them, a current will be generated.

So how did the frog float? Because frog is an diamagnetic object, when it is put into a magnetic field, it will generate corresponding current. If the magnetic field is strong enough, it will counteract gravity and float.

? Therefore, science is always so magical that we have the desire to explore, and science has also changed our lives and made our lives more colorful.
