Question

Transcranial magnetic stimulation (TMS) is a noninvasive techniqueused to stimulate regions of the human brain. A small coil isplaced on the scalp, and a brief burst of current in the coilproduces a rapidly changing magnetic field inside the brain. Theinduced emf can be sufficient to stimulate neuronal activity. Onesuch device generates a magnetic field within the brain that risesfrom zero to 1.1 T in 100 ms. Determine the induced emf within a circle oftissue of radius 2.0 mm and that isperpendicular to the direction of the field.

Explanation / Answer

use the fomrula: Emg=Magnetic Flux/Time = BAcos/Time cos= 1 so you can neglect it Just plug in your values. Remebers the units for the problemare in millivolts /qa-board/message-add.aspx?message_topic_id=507986 GOOD LUCK GOOD LUCK
