← ScienceWhich effect occurs within a MRI machine when its strong gradient magnetic fields switch rapidly?
A)Eddy current induction in conductors✓
B)Paramagnetic spin alignment saturates quickly
C)Ferrofluid overheating becomes uncontrolled
D)Radiofrequency pulse amplitude decreases exponentially
💡 Explanation
Eddy currents are induced because Faraday's law causes circulating currents within any conductive material exposed to a changing magnetic field. Therefore, conductive parts heat up, rather than parameter saturation or RF power dropping because the issue is electromagnetic induction.
