Magnetization relation to magnetic field applied

[igurman]

A few simple questions which I am not sure about, it's about NMR.

First sentence: "A magentic field B0 is applied on a sample, If the applied magnetic field B0 is stronger, the magnetisation of material is greater" . Would you say that sentence is correct? As I understood, magnetization is a property of the material, so it confuses me.

Second question is: does magnetization have only a longitudinal component? In which cases does it have a transverse one as well? and how does that contribute to NMR/MRI ?Thanks for assisting

Not true. We can and do magnetize and demagnatize materials using magnetic fields.

Perhaps you are thinking of the magnetic permeability which is a property of the material.
