<LATEST UPDATE>
Active Shielding .......Answer.........A coil of wire with an electrical
current running through it produces an electromagnetic field
opposing the static magnetic field to reduce the fringe field.
Bsub0 .......Answer.........The unit is used to describe the static
magnetic field.
Deflection .......Answer.........The amount of attraction an object
has to the static magnetic field.
Diamagnetism .......Answer.........A weakly repulsive force when
placed in a strong static magnetic field.
,age 2 of 75
Faradays, the Law of Induction .......Answer.........This describes
how electrical currents are produced in alternating magnetic
fields.
Ferromagnetism .......Answer.........An object with a strong,
attractive force in a strong static magnetic field retains a
magnetic field even when leaving the strong static magnetic
field.
Flux Lines .......Answer.........The gradient of magnetic densities
that move from the north pole of the static magnetic field to the
south pole.
Fringe Field .......Answer.........The magnetic field extends outside
the MR unit.
Gauss .......Answer.........A magnetic field unit of measurement.
,age 3 of 75
Horizontal Static Magnetic Field .......Answer.........A magnetic
field vector that is horizontal.
Lenz's Force .......Answer.........The process of non-ferrous objects
producing a magnetic field when moved through a strong static
magnetic field.
Magnetic Field Strength .......Answer.........The overall magnetic
field strength of the MR unit.
Magnetic Moment .......Answer.........Each hydrogen proton
produces a particular magnetic field.
Magnetohydrodynamic Effect .......Answer.........When patients
are exposed to a strong static magnetic field, their blood
becomes magnetized. This causes a high T wave in their cardiac
cycle.
, age 4 of 75
Paramagnetic .......Answer.........A weakly attractive force when
placed in a static magnetic field.
Passive Shielding .......Answer.........Using magnetically conductive
materials in an MR unit reduces the fringe field.
Pauli Exclusion Principle .......Answer.........The principle describes
the atom structure and the types of magnetism (ferromagnetism,
paramagnetic, diamagnetism...).
Rotational Force .......Answer.........A force that aligns objects
affected by the static magnetic field to its flux lines.
Spatial Gradient Magnetic .......Answer.........The changing
magnetic field strength was demonstrated at different distances
from the MR unit.
