and we have nails and screws where we can hang any item which is lying around in our house. Well to understand that we first need to know what exactly is a magnetic hook, how does it magnetic properties come into action, and why is it considered better than all the other remaining opti...
1.The force produced by a magnetic field. 2.The properties or effects of magnets:Magnetism causes a compass needle to point north. Did You Know?The force known asmagnetismis caused by the motion of electrons. As these tiny, negatively charged particles revolve around an atomic nucleus, they ...
interviews people who have achieved "superhuman" feats, such as Mark Beaumont, who cycled around the world in 78 days, and Diana Nyad, who completed a 110-mile swim from Cuba to Florida without a shark cage at the age of 64.
Most of our daily experience with magnetic fields involves either sticking things to our refrigerator, or perhaps using a compass to point north. The latter shows the existence of magnetic fields generated by our planet. Our sun also creates a vast magnetic...

When poles flip, the magnetic field won’t be gone completely; it will just be alarmingly weaker, down to around 10% of its present strength. Plus, it can also mean the temporary presence of several north and south poles existing simultaneously. ...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. ...
Usually, magnets are strong enough for you to use one magnet to push another around on top of a table and never have them touch each other. Give it a try! When magnets pull together or bring something closer, it is called attraction. When magnets push themselves or things away, they rep...
The materials are simple. We need a wooden ruler that has a groove in the top in which a steel ball can roll easily. Any piece of wood or aluminum or brass with a groove will work. We chose the ruler because they are easy to find around the house or at school or at a local stat...
