But how do magnets work in the first place? Magnetism is the force exerted by magnets—objects that repel or attract each other. This powerful physical phenomenon is one component of electromagnetism, one of the fundamental forces of nature. The motion of electrically charged particles found in...

One practice involves passing a magnet over the cows' food to remove metal objects. Another is to feed magnets to the cows. Long, narrow alnico magnets, known as cow magnets, can attract pieces of metal and help prevent them from injuring the cow's stomach. People, on the other hand, ...
of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.
magnets slightly attract liquid oxygen and other materials magnets slightly repel water, carbon and boron and so on Now, the fun begins. We start to ask the question, "Why?" This is what scientists continually do - try to figure out why things behave the way they do. Once we figure th...
Why do they attract or repel each other, depending on their positioning? And what makes neodymium magnets so much stronger than the ceramic magnets we played with as children? To understand the answers to these questions, it helps to have a basic definition of a magnet. Magnets are objects ...
If you have a positive electrical charge and a negative electrical charge, they attract one another like the opposite poles of two magnets—or like your body and Earth. If you pull them apart, you have to "do work" against this electrostatic force. Again, just like with climbing steps, ...
And what about this one:magnetsare pieces of metal which attract certain other kinds of metal - for example, iron or steel. The Earth itself has amagneticforce. Neil Birds use it to help them navigate over thousands of miles...
Thus, magnets work on this principle ofmagnetic fields. Another point to make a note of is this – “Like poles repel” and “Opposite poles attract” The north pole of one magnet will repel the north pole of another magnet, but will attract the south pole of the same magnet. ...
First, gravity is a force that causes objects to attract one another. The simplest way to understand gravity is through Isaac Newton's law of universal gravitation. This law states that every particle in the universe attracts every other particle. The more massive an object is, the more ...
