Forces and Interactions Magnetism How do the poles of two bar magnets interact with each other? Here we have a retort stand, some string and 2 bar magnets. Let’s tie the string to one bar magnet and attach it to the retort stand so that it hangs freely. Now let’s observe what happens when the north pole of a bar magnet is brought closer to the north pole of the hanging magnet. Wow! The hanging magnet moves away – the north poles repel each other. Can you guess what happens what happens when the south pole of the bar magnet is brought closer to the north pole of the hanging magnet. You guess it! They attract each other! Now let’s observe what happens when the north pole of the bar magnet is brought closer to the south pole of the hanging magnet. Look! The hanging magnet moves closer – they attract to each other. Let’s try that with the South Poles of the magnet. Cool! The south poles repel each other. Opposite poles of magnets attract each other and like poles of magnets repel each other. www.ngscience.com
