The effects of time varying magnetic fields can include all of the following EXCEPT which one?

Explanation:
Time-varying magnetic fields, such as the gradient fields used during MRI, can induce electrical activity in tissues. This can lead to sensations like tingling from peripheral nerve stimulation and sometimes nausea or headache from vestibular or discomfort effects related to the rapidly changing fields. These are the direct sensory or discomfort effects of gradient switching. Bulk heating or a noticeable increase in body temperature, on the other hand, comes from RF energy deposited into tissue (the SAR effect), not from the gradient switching itself. So warmth or a rise in body temperature is not a direct effect of time-varying magnetic fields.
