(N/A) Electromagnetic refers to the production of electric current in a coil under the influence of a magnetic field. Induction refers to the process of generating an electrical flow in a conductor without direct physical contact with a magnetized body.
Factors affecting the magnitude of induced current:
$(i)$ Number of turns in the coil.
$(ii)$ Strength of the magnetic field.
$(iii)$ Relative speed of the magnet with respect to the coil.
Rule: Fleming's Right-Hand Rule.
Statement: Stretch the thumb, forefinger, and middle finger of your right hand such that they are mutually perpendicular to each other. If the forefinger points in the direction of the magnetic field and the thumb indicates the direction of motion of the conductor, then the middle finger will point in the direction of the induced current.
Practical application: Electric Generator.
