2 Objectives Demonstrate an understanding of the principles of magnetism and electromagnetics. Show how a solenoid is constructed and how it operates. Calculate the magnetic flux, magnetomotive force, and flux density in a closed core. State the relationships among reluctance, absolute permeability, and relative permeability. Explain the relationship between magnetic field intensity and flux density.
