MRSO

Static magnetic field

TermDefinition
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. Active Shielding
The unit is used to describe the static magnetic field. Bsub0
The amount of attraction an object has to the static magnetic field. Deflection
A weakly repulsive force when placed in a strong static magnetic field. Diamagnetism
This describes how electrical currents are produced in alternating magnetic fields. Faradays, the Law of Induction
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. Ferromagnetism
The gradient of magnetic densities that move from the north pole of the static magnetic field to the south pole. Flux Lines
The magnetic field extends outside the MR unit. Fringe Field
A magnetic field unit of measurement. Gauss
A magnetic field vector that is horizontal. Horizontal Static Magnetic Field
The process of non-ferrous objects producing a magnetic field when moved through a strong static magnetic field. Lenz's Force
The overall magnetic field strength of the MR unit. Magnetic Field Strength
Each hydrogen proton produces a particular magnetic field. Magnetic Moment
When patients are exposed to a strong static magnetic field, their blood becomes magnetized. This causes a high T wave in their cardiac cycle. Magnetohydrodynamic Effect
A weakly attractive force when placed in a static magnetic field. Paramagnetic
Using magnetically conductive materials in an MR unit reduces the fringe field. Passive Shielding
The principle describes the atom structure and the types of magnetism (ferromagnetism, paramagnetic, diamagnetism…). Pauli Exclusion Principle
A force that aligns objects affected by the static magnetic field to its flux lines. Rotational Force
The changing magnetic field strength was demonstrated at different distances from the MR unit. Spatial Gradient Magnetic
The magnetic field that aligns hydrogen nuclei parallel or anti-parallel. Static Magnetic Field
When placed in a strong static magnetic field, a stronger attractive force than superparamagnetic, but not as strong as ferromagnetism. Superparamagnetic
The potential effects of a static magnetic field on the offspring of individuals exposed to it. Teratogenic
The unit of measurement is used to describe the static magnetic field. Tesla
The attractive force of an object as it translates through the static gradient magnetic field. Translation Force
The direction of the static magnetic field. Vector
A magnetic field vector that is vertical. Vertical Static Magnetic Field

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
