Question 3:

Which physical property of atoms is utilized in an MRI scanner?

A) Electric charge
B) Mass
C) Spin
D) Temperature

Show Answer

Explanation: The correct answer is C) Spin. An MRI scanner utilizes the spin property of atomic nuclei, specifically the protons, to create images. By subjecting the body to a strong magnetic field and applying radio frequency pulses, the alignment and relaxation of the spins are detected to generate the images.
