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 ...

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

9 thoughts on “ Magnetic Gearbox Design Improvements Are Toothless But Still Cool ” The Commenter Formerly Known As Ren says: October 8, 2022 at 4:37 pm Enjoyable ...

Coil Design. The magnetic field in solenoid coils is given in Equation-9 and Equation-10 for Helmholtz coil pair. B is the magnetic field, µ is the permeability, ...

Running at 75 KHz, this design has about 40% less loss than the 18AWG coil, even though the dc resistance is more than twice as high. The curves in Fig. 2 show this, and above the fourth harmonic ...

The magnetic field generated by the coil is typically in the range of 1 to 4 Tesla, which is a huge magnetic field that will have a detrimental effect on some of the electrical equipment such as power ...

New coil design features make it possible to get high-quality image of the whole mouse easily. First of all, the coil size is specially adapted for scanning a mouse, which helps to avoid extra noize.

The magnetic field orientation can be easily programmed by controlling the current direction in the coil. This helps to create north-south pole patterns on the card. The narrower the air gaps between ...

The term “voice coil,” a non-commutated dc linear actuator, comes from one of its historically first applications: vibrating the paper cone of a loudspeaker. Today they are used for a wide ...

Magnetic radial bearings have a stator and rotor. The surface area of the magnetic poles, number of coil windings, air-gap dimensions, and applied voltage and current all affect bearing ratings.
