100% Correct Answers
Static Magnetic Field
✓ ~~> -poses risks to our patient that involve materials with specific
properties
Magnetic Properties
✓ ~~> -when place in a strong magnetic field, molecules demonstrate
behaviors that depends on their quantum state and temperature
Diagmagnetism
✓ ~~> -demonstrates a weak repulsive force in the presence of a strong
static magnetic field

✓ ~~> -demonstrates a strong attractive force in the presences of a
static magnetic field
-this attractive force is retained in the ferromagnetic object after a period of
time even after leaving the static field
Basic Units of Measurement
✓ ~~> -static magnetic field
-magnetic flux
-millitesla (mT)
-Gauss (G)
-Tesla (T)
Static Magnetic Field
✓ ~~> -this refers to the direction and strength of a static magnetic field
-represents as B0 (B zero)
Magnetic Flux
✓ ~~> -the magnetic force that encompasses a magnetic source
Millitesla

✓ ~~> -mT
Gauss (G)
✓ ~~> -1 mT
-5 G = 0.5 mT
Tesla (T)
✓ ~~> -10,000 Gauss = 1 T
Lines of Flux
✓ ~~> -invisible lines
-fringe field
-vector directions
-short bore vs long bore
Invisible Lines
✓ ~~> -force that travels from the north pole of a magnet to the south
pole
Fringe Field

✓ ~~> -field that extends outside the MR unit
-varies strength the closer you get to the MR unit
Vector Directions
✓ ~~> -vertical or horizontal
Short Bore vs Long Bore
✓ ~~> -short bore have steep spatial gradients
Magnetic Spatial Gradient
✓ ~~> -fringe field extending outside MR unit
-used to describe the change in strength of the magnetic field as we get
closer to the MR unit
-like an onion has layers, so does a magnetic field
-measured in dB/dx
-in other words, T/m or G/cm
-1 T/m = 100 G/cm
