The grad-B drift can be considered to result from the force on a magnetic dipole in a field gradient.
12.
MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the inside of the body.
13.
PPMs work in field gradients up to 3, 000 nT / m, which is adequate for most mineral exploration work.
14.
A "'pulsed field gradient "'is a short, timed pulse with spatial-dependent field intensity.
15.
PPMs work in field gradients up to 3, 000 nT m " 1 which is adequate from most mineral exploration work.
16.
To sensitize MRI images to diffusion, instead of a homogeneous magnetic field, the homogeneity is varied linearly by a pulsed field gradient.
17.
"' Quadrupole splitting "'reflects the interaction between the nuclear energy levels and surrounding electric field gradient ( EFG ).
18.
The column consists of steel wool which increases the magnetic field gradient to maximize separation efficiency when the column is placed between the permanent magnets.
19.
Usually these field gradients are pulsed, and it is the almost infinite variety of RF and gradient pulse sequences that gives MRI its versatility.
20.
In addition, near-field gradients have been exploited to individually address two ions separated by approximately 4.3 micrometers directly with microwave radiation.
