Question

Transcranial magnetic stimulation (TMS) is a noninvasive method for studying brain function, and possibly for treatment as well. In this technique, a rapidly changing magnetic field is applied to a person’s brain. This can cause a finger to twitch, a bright spot to appear in the visual field, or a feeling of complete happiness to overwhelm a person. If the magnetic field changes at the previously mentioned rate over an area of 1.75 10-2 m2, what is the induced emf?

    Answer:

    525 V

    Explanation:

    A = Area = 1.75\times 10^{-2}\ m^2

    \dfrac{dB}{dt} = Rate of change of magnetic field = 3\times 10^4\ T/s (assumed)

    Induced electromotive force is given by

    E=A\dfrac{dB}{dt}\\\Rightarrow E=1.75\times 10^{-2}\times 3\times 10^{4}\\\Rightarrow E=525\ V

    The induced electromotive force is 525 V
