Magnetic Resonance Imaging (MRI) relies on the precise performance of gradient coils to achieve high spatial resolution and rapid imaging sequences. These coils generate spatially varying magnetic ...

In this article, I want to use an MRI (magnetic resonance imaging) medical scanner design as a familiar example for what needs to be done in a power supply design architecture to allow it to function ...

One problem with high frequency magnetic design is how to sort out the losses that contribute to a part's efficiency. With the exception of dc resistance, these losses are very difficult to separate ...

Early in the planning process of a magnetic component, designers select a core, which drives all of the component variables. The core then becomes an element in a series of calculations and is used to ...

Researchers from ITMO University developed and tested an MRI coil providing high-resolution imaging of the whole body of a mouse. Such coils are used in preclinical testing, as well as in imaging of ...

Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object approaching the sensor changes magnetic flux through ...

Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

More-powerful controllers and better software lead to broader applications for magnetic bearings. Magnetic-bearings, which support shafts with magnetic levitation rather than mechanical contact, have ...
