Content Statement
... Concept: Magnetic fields exist around magnetic objects. If a second magnetic object is placed in the field, the two objects experience magnetic forces that can attract or repel them, depending on the objects involved. Magnetic force weakens rapidly with increasing distance. Magnetic field lines can ...

The Physics of Magnetic Resonance Imaging
... The external magnetic field is usually provided by large super conducting magnets operating at –269 o C and giving a field of 2T. The change in the remitted signal depends on the number of hydrogen nuclei present in the volume of the body examined. Magnetic resonance imaging (MRI) was first used in ...
