Inductive charging is used to wirelessly charge electronic devices ranging from toothbrushes to cell phones. Suppose the base unit of an inductive charger produces a 1.20 ✕ 10−3 T magnetic field. Varying this magnetic field magnitude changes the flux through a 12.0-turn circular loop in the device, creating an emf that charges its battery. Suppose the loop area is 3.75 ✕ 10−4 m2 and the induced emf has an average magnitude of 5.40 V. Calculate the time required (in s) for the magnetic field to decrease to zero from its maximum value.

Find the magnitude of the average emf (in V) induced in his wedding ring, given its diameter is 2.26 cm and assuming it takes 0.210 s to move it into the field.
- Transcranial magnetic stimulation (TMS) is a noninvasive technique used to stimulate regions of the human brain. A small coil is placed on the scalp, and a brief burst of current in the coil produces a rapidly changing magnetic field inside the brain. The induced emf can be sufficient to stimulate neuronal activity. One such device generates a magnetic field within the brain that rises from zero to 1.1 T in 100 ms. Determine the magnitude of the induced emf within a circle of tissue of radius 1.6 mm and that is perpendicular to the direction of the field. e = mVA technician wearing a circular metal band on his wrist moves his hand into a uniform magnetic field of magnitude 2 T in a time of 0.21 s. If the diameter of the band is 5.2 cm and the field is at an angle of 59° with the plane of the metal band while the hand is in the field, find the magnitude of the average emf induced in the band. 0.0061 V 1.0417 V 0.0417 V 0.0104 VInductive charging is used to wirelessly charge electronic devices ranging from toothbrushes to cell phones.
