A technician wearing a brass bracelet enclosing area 0.00500 m2 places her hand in a solenoid whose magnetic field is 4.30T directed perpendicular to the plane of the bracelet. The electrical resistance around the circumference of the bracelet is 0.0200 N. An unexpected power failure causes the field to drop to 1.29 T in a time of 21.0 ms. (a) Find the current induced in the bracelet. A (b) Find the power (P) 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
