How Can Magnets Move Things Without Touching Them?
Originating from Earth’s core and atoms themselves, magnetism is the invisible force that shapes our everyday lives. Here’s how magnets actually work.
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 ...
magnet is any object that has a magnetic field. It attracts ferrous objects like pieces of iron, steel, nickel and cobalt. In the early days, the Greeks observed that the naturally occurring 'lodestone' attracted iron pieces. From that day onwards began the journey into the discovery of magn...
magnetic field that attracts metal objects such as iron and steel. This makes magnets useful in car ignitions and toys. Certain metal objects will move if they are placed near a magnet, but others will not. To make objects move with a magnet attach a piece of metal, or another magnet, ...

But in the quantum mechanics view, electrons emit undetectable, virtual particles that tell other objects to move away or come closer, Walker said. Although these two theories help scientists understand how magnets behave in almost every circumstance, two important aspects of magnetism remain ...
Can magnets make things float? Magnetism is a strange force. It is able to push and pull objects without touching them. ... Using the correct number and placement of magnets,almost any object can be induced to float, seemingly weightless above the ground. ...
There are also round magnets, such as cup magnets. Cup magnets still produce a magnetic field, but they feature a round shape — as well as a small size — that makes them ideal for certain applications. What are cup magnets exactly, and how do they work? Overview of Cup Magnets Cup ...
Dimagnetism refers to an object's tendency to generate a weak magnetic field in opposition to a magnetic field applied to it. Dimagnetic objects repel magnets. Water is dimagnetic, although it is not as strongly dimagnetic as carbon-graphite. The presence of a strong magnetic field can cause...
