The coil of a generator has a radius of 0.14 m. When this coil is unwound, the wire from which it is made has a length of 5.4 m. The magnetic field of the generator is 0.10 T, and the coil rotates at an angular speed of 35 rad/s. What is the peak emf of this generator?(adsbygoogle = window.adsbygoogle || []).push({});

so i have:

r= .14m

L= 5.4m

B= .10T

w=35 rad/s

now i thought i would do:

emf= BLv

v=rw... v= .14m(35 rad/s)

emf= (.10T)(5.4m)(.049m/s)= .02646

and peak emf= (square root 2)(emf)= .0374...

this problem is wrong the way i tried it, but i'm not sure what i should do differently
