A solenoid is constructed with a core of ferromagnetic material, compared to an air core of the same geometry. Explain how the magnetic field is influenced and provide the formula for both.
💡 Hint: Consider how materials affect magnetic permeability.
You have two solenoids of equal length but different turn densities; one has twice the turns per unit length compared to the other. Discuss the differences in magnetic field strengths.
💡 Hint: Review how turns relate to the output field.
