While superconductive magnets are expensive, the strong magnetic field allows for the highest-quality imaging, and superconductivity keeps the system economical to operate. The Other Parts of an MRI Machine Two other magnets are used in MRI systems to a much lesser extent. Resistive magnets are ...
The most powerful permanent magnets available produce fieldsabout 1.5 tesla. While that's hardly shabby – magnets of that strength are used in MRI machines – it's still pretty limiting for many scientific and other applications. Can you fly using magnets? If you want something to levitate, y...
torch in the z-axis direction (upwards/north), how will two permanent magnets, axially aligned N-S to N-S in the x-direction (left to right across the page/screen) interact with the plasma to deflect it, specifically, at what angle would the plasma be deflected at in the y-direction...
A compass needle isn't nearly as strong as many of the permanent magnets used today. But the physical process that magnetizes compass needles and chunks of neodymium alloy is essentially the same. It relies on microscopic regions known as magnetic domains, which are part of the physical structu...
Some Magna Doodles also come with "shape stampers," which are simply magnets in shapes like diamonds, triangles and circles. Writing is but one use of the Magna Doodle. You must also be able to erase it, so let's look at the eraser. Magnetic Eraser Magnetic eraser The magnetic ...
Electromagnets work just as well as permanent magnets. In fact, they are even more useful, because you can turn them on and off. You'll find electromagnets in hard drives, speakers and even in sophisticated equipment like MRI machines and CERN's Large Hadron Collider in Geneva, Switzerland. ...
Yes, artificial magnetic fields have a wide range of applications, including in medical imaging, particle accelerators, and magnetic resonance imaging (MRI) machines. They are also used in everyday devices such as speakers, motors, and generators.Similar...

Permanent magnets had not been used before because scientists thought that they would not create enough levitating force. The Inductrack design bypasses this problem by arranging the magnets in a Halbach array. The magnets are configured so that the intensity of the magnetic field concentrates above...
Devices that run using electrical power (phones, computers, dishwashers and coffee machines) are used on a daily basis and make our lives easier. Electricity is brought to our homes with the use of electrical generators. The modern electrical generators
