I need to be able to find the EMF or E field outside a coil (solenoid) for my test tonight.I know EMFintegral( E*dL) but I don't know how to relate it to a solenoid.Thanks for the help
If the magnetic field is constant (i.e., the current is DC and constant) there is no E field. If it's AC, from anaemic1's answer in the ref, E -mu*n*I*omega*R^2*cos(omega*t)/(2r), where n is turns per unit length, r is radial distance, R is solenoid radius and omega is AC frequency. If you're only interested in the amplitude, omit the cos(omega*t) term.
