Induction can be simply defined as the effect of 1 thing on the other.
eg:
Electromagnetic Induction is the effect of the Electric/Magnetic field produced due to moving charges/magnet (respectively) in a body to another body or loop lying in the viscinity.
Electriomagnetic Induction produces EMF (electromotive force, i.e. potential difference) in the conductor near by and if the ends of the conductor are attached with a resistance, the current will flow, without resistance(ideal case) the loop will get short-circuited.
