Which physiological effect is predominantly reported in experiments involving high gradient fields?

In the context of high gradient magnetic fields, the physiological effects observed can encompass a variety of phenomena. High gradient fields are commonly associated with MRI systems, particularly during imaging sequences that involve rapid changes in magnetic field intensity.

Thermal damage can occur due to the heat generated from RF (radiofrequency) energy absorption in the body. However, high gradient fields specifically can lead to rapid and significant changes in local magnetic field strength, which may not primarily cause thermal damage but can still contribute to overall safety considerations.

Acoustic noise is another critical aspect of high gradient fields. The operation of gradient coils generates vibrations, creating sound waves that can result in high sound levels during MRI scans. This noise can be uncomfortable and poses a consideration for patient safety and comfort.

Magnetophosphenes are visual sensations experienced when the eye is exposed to a strong magnetic field. The high gradient fields can activate retinal cells, leading to the perception of light or visual disturbances even in the absence of optical stimuli. This phenomenon underlines the effects that high magnetic gradient fields can have on sensory perception.

Given that high gradient fields can cause thermal effects, produce significant acoustically induced noise, and result in visual sensations like magnetophosphenes, it is accurate to state that all the
