Atechnician wearing a brass bracelet enclosing area 0.00500 m2 places her hand in a solenoid whose magnetic field is 2.70 t directed perpendicular to the plane of the bracelet. the electrical resistance around the circumference of the bracelet is 0.0200 . an unexpected power failure causes the field to drop to 0.81 t in a time of 19.0 ms. (a) find the current induced in the bracelet. a (b) find the power delivered to the bracelet. (note: as this problem implies, you should not wear any metal objects when working in regions of strong magnetic fields.) w
