美国小学生口语对话:How do magnets work? 磁铁是如何工作的?所有科学家都遵循一套称为科学方法的步骤。他们用这种方法来检验自己的想法,看看是否正确。首先,他们观察周围的世界。接下来,他们做出假设,或者有根据的猜测,来解释他们所看到的。然后他们进行实验来验证
The work always starts by simple observation (that's the fancy word for playing around with the stuff!). That's why it's so important to have some "hands-on" experience with magnets. Have you taken two magnets and tried to push like poles together? How far away do you start to feel...
We have all played with magnets from time to time. Every time you do, you have asked yourself ‘how do magnets work?’ Many of us understand that magnets have two different charges and that like charges repel each other, but that still does not explain how a magnet works. Below is an...
或者说的感情强烈一点:磁铁他妈的到底是怎么工作的?
Originating from Earth’s core and atoms themselves, magnetism is the invisible force that shapes our everyday lives. Here’s how magnets actually work.
Physicists have some understanding of how magnets function. However, some phenomena that underlie magnetism continue to elude scientific explanation. Exactly how do magnets work? Large-scale magnetism, like the kind observed in bar magnets, results from magnetic fields that naturally radiate from the ...
When a magnetic compass is placed at different points on a magnetic line of force, it aligns itself along the tangent to the line of force at that point. These are just some of the basic concepts of magnetism. One cannot possibly grasp the depth and appreciate the versatility of magnets wi...
Magnets : How do they work? When a ferromagnetic material (a material that is attracted to magnets) comes into contact with the magnet, the domains in this material align themselves with the domains in the magnet. Thus, the atoms in these materials, like steel, for example, temporarily tend...
Scissors, tape, round plastic container, two magnets, ruler, rubber bands, steel washers. STEP 1 Cut off a piece of tape and use it to tape the round container firmly to the work surface. The round container will act as a pivot, or the balancer. ...
Magnets are a direct result of the physics taking place at the atomic level (i.e. quantum level) within the material of the magnet. Magnetic fields are polarized with two magnetic poles called North and South. One of the interesting features of a magnet is that, if you break it into ...
