Magnetic cores are doughnut-shaped magnetic materials that are used with inductors, transformers, and electromagnets. They are also used as computer memory elements. Magnetic cores are made of metal ...

At higher frequencies, a more successful strategy for preventing eddy-currents is to form cores by pressing together magnetic-material powders in an insulating binder. Representative commercial core ...

Core memory, magnetized memory using tiny magnetic rings suspended on a grid of wires, is now more than five decades obsolete, yet it exerts a fascination for hardware hackers still. Not least ...

Magnetic materials are always attracted towards a magnet ... If you bring a north pole and a south pole together, they will attract. Earth's core contains liquid iron which moves around.

These devices could serve as valuable tools for biomedical research and may have potential for clinical applications in the ...

(High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic ...

The magnetic core is magnetostrictive ... The team included researchers affiliated with MIT's departments of Materials Science and Engineering, Electrical Engineering and Computer Science ...

Earth, our rocky, watery oasis in the cosmos is the ideal place for life to flourish for a number of reasons. We sit at just the right distance from our home star for liquid water to exist on the ...

The Earth has a magnetic field, generated by processes from deep within the planet. Molten metallic material flows in the ...

Part I deals with a brief history of magnetism and magnetic materials along with their role in modern society ... you will be asked to authorise Cambridge Core to connect with your account. Find out ...

The Korea Research Institute of Standards and Science (KRISS) has, for the first time in the world, generated and controlled ...
