但是如果毛细作用足够强大，可以克服重力，把水吸上来，它也可以防止水落回碗里。Thenthereareversionswithmagnets,likethissetoframps.还有带磁铁的版本，比如这组坡道。The ball is supposed to be pulled upwards by the magnet at the top, fall back down through the hole, and repeat the cycle.球应该被顶...
Magnets have been one of the most useful materials discovered and have been the source for much wonder and entertainment. Since their discovery thousands of years ago, people have found uses for magnets in all types of equipment. From compasses to cabinet doors, most people encounter magnets on ...
But on a long trip, well, there are lots of opportunities to make small mistakes, and small mistakes can add up, leading the mole rat far from where it wants to be. So on a long trip, a magnetic navigation system is better, more useful, since earth's magnetic field is stable, a ...
Why are magnets non-contact forces? How is electromagnetism created? Why is there only magnetic force when there's velocity? Why do electrons move in a circuit? Why does the magnetic force depend on velocity? Why is motion a keyword for magnetism?
How are magnets used in particle accelerators? Why doesn't electromagnetism affect light? Why is understanding antimatter important? How did Michael Faraday contribute to physics? How is electromagnetism created? How was antimatter discovered?
