This interesting phenomenon was first discovered by the shark defense research company of the United States. In an experiment, the staff accidentally dropped a magnet into the pool where the sharks were kept. As a result, the sharks in the pool were scared away. This interesting phenomenon attracted the staff’s attention. He wondered whether the fierce sharks were afraid of magnets?
So the researchers did a series of experiments to prove that sharks really fear magnets. One of them held a lemon shark tightly, and the other approached it slowly with a magnet (the magnet was blocked by the staff). However, the lemon shark still showed strong discomfort, struggled violently and fled to the distance.
So they think that the magnet interferes with the shark’s navigation organs and causes strong discomfort. If so, can we just tie a magnet to our waist to avoid shark attack when diving?
Indeed, in their subsequent experiments, they placed a circle on the bottom of the sea with magnets and bricks, and put food on them.
After many experiments, the shark only ate the food in the brick, and the food in the magnet didn’t move, while other small carnivorous fish obviously didn’t fear the magnet, they ate all the food here.
Obviously, the magnet can indeed affect sharks. In fact, this is mainly due to the influence of the ampulla of Lauren’s. This is an organ in front of the shark’s nose (some dark holes in front of the nose). This organ can feel even one billionth of the change of voltage, and can feel the changes of the surrounding environment by feeling the very subtle changes of magnetic field. It’s like our eyes. We get information about our environment by perceiving light, but when we are exposed to strong light, we instinctively avoid it, and so do sharks.
Some people may have seen the curiosity experiment. They tested the above results in an aquarium with two magnets, one large and the other small, but the shark didn’t seem to be affected by the magnets. At first, the experimenter placed the magnet around the shark, and the shark didn’t respond. Later, when the magnet was placed in front of the shark, the shark was scared away. Finally, when the magnet was placed in any position, the shark didn’t respond.
So they came to the conclusion that whether sharks are affected by magnets may depend on their mood… Two seemingly similar experiments seem to have come to two completely different conclusions. In Xiaobian’s opinion, maybe the shark in the aquarium is kept for too long, and the function becomes insensitive? Or is it because flipping sharks over in the first experiment really makes them more sensitive to magnetic fields? Do you think sharks are afraid of magnets? Welcome to leave a message for discussion.
