During transcranial magnetic stimulation (TMS) treatment, a magnetic field typically of magnitude 0.55 T is produced in the brain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 85 μs . Assume that the magnetic field is uniform over a circular area of diameter 2.1 cm inside the brain. What is the magnitude of the average induced emf | E | around this area in the brain during the treatment?

Answer:   [a]:   "slate" .

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
