Researchers at ETH Zürich have built the most powerful miniature superconducting magnets ever demonstrated, ...

Permanent magnets used for motors require high energy density, or high levels of magnetism and coercivity. Coercivity is a magnet’s ability to maintain its current level of magnetism, despite exposure ...

What is an axial-flux permanent-magnet motor? Types of AFPM motors. Benefits of in-wheel traction motors. All motors can change their inherent energy into mechanical energy. The basic function of a ...

There are currently several superconducting materials used for design and fabrication of high-field magnets. 1 The most widely established of them—low-temperature superconductor NbTi—is the workhorse ...

The top magnetic assembly manufacturers are not necessarily the largest companies by revenue. More often, leadership in this market is defined by the ability to serve technically demanding customers ...

Developed at the U. S. Ames National Laboratory, the novel magnetocaloric heat pump utilizes gadolinium as the working medium and reportedly matches current vapor-compression heat pumps for weight, ...

A team of researchers has proposed a new concept for magnet-based memory devices, which might revolutionize information storage devices owing to their potential for large-scale integration, ...

The first storage media — paper tape and punched cards — were inefficient, slow and bulky. These gave way to magnetic storage: core memory, drums and, finally, hard drives. For backup, there were ...
