I have worked my way through this question, and I still get a wronge answer. A piece of copper wire is formed into a single circular loop of radius 9 cm. A magnetic field is oriented parallel to the normal to the loop, and it increases from 0 to 0.70 T in a time of 0.45 s. The wire has a resistance per unit length of 3.3 10-2 /m. What is the average electrical energy dissipated in the resistance of the wire. r= 9cm= .09m change in t= .45s B= .70T restitance per unit length= 3.3 x 10^-2 N= 1 emf=-80.15 mag flux 178.12 I figured R to = .01866 I = 4295.25 P= -344264.29 (I *EMF) E= 344264.633 (pt) anyone know where I went wrong?
