Methods of producing image information from objects To produce image information from an object it is subjected to a continuous static magnetic field along a Z axis and to sets of sequences of orthogonal gradients G x , G y and G z to the magnetic field. Spins in a selected plane (the ...
Derive the expression for the instantaneous value of the emf induced in the coil. View Solution A coil is rotated in a uniform magnetic field about an axis perpendicular to the field. The emf induced in the coil would be maximum when the plane of coil is : View Solution A coil of are...

In addition, each coil extends a length equal to a 1/3 the length of the cylinder. Write a program that defines the magnetic field in the centerline of the cylinder (on the z axis) and plots it against z (from –l to l, where l is the length of the cylinder). Note that the ...
The degree of inversion, i.e., the concentration of the M2 + ions in the octahedral sites, depends strongly on the synthetic conditions,50 which, therefore, also affect the observed magnetic properties.51 NiFe2O4 is a nearly perfect inverse spinel, due to the substantial ligand field ...
Magnetic susceptibility (ꭓ) is an intrinsic property of materials, and it is defined as the magnetic response of a material or substance when it is placed in an external magnetic field. From: European Journal of Radiology, 2021 About this pageSet alert ...
Starting from the basic physical principles,in the case of arbitrary coil spacing of two coaxial electric circular coil,we have launched the general expression of magnetic induction intensity at any point on the axis.We determined the coil spacing of the optimum magnetic field uniformity,using the ...
A difficult problem concerns the determination of magnetic field components within an experimentally inaccessible region when direct field measurements are not feasible. In this paper, we propose a new method of accessing magnetic field components using
The gradient system consists of a set of gradient coils, typically one for each axis (x, y, and z), for creating (usually linear) variations of the magnetic field in a specified direction. A gradient that is applied parallel to B0, for example, will cause the magnetic field to be ...
