A 187‑turn circular coil of radius 3.77 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 18.7 Ω resistor to create a closed circuit. During a time interval of 0.199 s, the magnetic field strength decreases uniformly from 0.585 T to zero. Find the energy E in millijoules that is dissipated in the resistor
