Magnets and Motors : National Science Resources Center :If you were to tell people that the technology exists to manipulate the workings of people's brains, they may not believe you. That sort of thing is the stuff of cheap sci-fi B movies. If someone in the real world were to try to develop it, that's exactly the sort of scenario where they'd send James Bond in to stop them before it got too far. But the fact is that this technology genuinely exists and is widely used in neuroscientific research. It is known as Transcranial magnetic stimulation , or TMS, and as the name suggests it stimulates the brain through the cranium using magnetism. Magnets and the brain work together a lot.
Magnets and Motors : Student Activity Book
The invisible forces of magnetism are at work all around us, even as you read this sentence. To understand this concept, and how magnets work, can be difficult for students. Most of these fun, entertaining books are geared for students in kindergarten through third grade. They equip students with a solid understanding of concepts such as attraction, repulsion, and poles as well as different types of magnets like compasses, electromagnets, and more. A and includes the same concepts found in the booklist such as magnets, attraction, repulsion, poles, and much more.

Last updated: September 26, S cience is our understanding of how the world works—and generally the world works fine whether we understand it or not. Take magnetism , for example. People have known about magnets for thousands of years and they've been using them practically, as compasses, for almost as long. The ancient Greeks and Romans knew as well as we do that lodestone an iron-rich mineral can attract other pieces of iron, while the ancient Chinese were making magnetic compasses set in intricate wooden inlays for their practice of Feng Shui the art of carefully arranging a room thousands of years before interior designers came on board. Science can sometimes be slow to catch up: we've only really learned how magnetism works in the last century, since the world inside atoms was first discovered and explored.
A coil of wire becomes an electromagnet when current passes through it. The electromagnet interacts with a permanent magnet, causing the coil to spin. Give the coil a spin to start it turning. You might also try adjusting the distance separating the paper-clip cradles: This may affect the quality of the contact between the coil and the cradles. You might need to squeeze the unfolded ends of the paper clips to ensure that the aluminum foil is making a good electrical contact.
