Answer 2

mr=magnetic resonance's

so every material WHO exposed to a magnetic medium will be polarized in different way because he have a different molecules in specific mod of arrangement and the inspector of the moving electrons

will see a different behavior if its different materials as you asked

Answer 3

because the particles have a lot more time to react, therefore this increases the amount of difference that is produced in that time. If the time was shortened then there would not be a larger difference and the molecules would have a smaller impact.
