Are the accelerated charges the real reason for the magnetic induction?
Yes, this explanation works in cases where the EMF is due to electric current in a stationary circuit changing in time. Magnetic flux is proportional to current, so according to the Faraday law, ...

Induced E.M.F without changes in magnetic flux
You still have the Lorentz force $F=q*v*B$ if v is perpendicular to B. If you measure the voltage at the end of the wire you have an enclosed area with the wire and the voltmeter, otherwise there is ...
