The design of magnetic resonance imaging (MRI) gradient coils is a critical element in optimising image quality and system performance. These coils generate spatially varying magnetic fields, which ...

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 ...

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 ...

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 ...

Storing information through magnetic patterns was first demonstrated to record audio. Since then, this concept has been applied for different products like floppy disks, audio/video tapes, hard disks, ...

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 ...

Big, innovative breakthroughs often result in game-changing technologies. Smaller incremental improvements in essential material components can similarly lead to significant performance and efficiency ...

Explore key insights into miniature circuit breakers, including how they differ from fuses, what selection criteria to consider and their coordination with protective devices for optimal electrical ...
