← ScienceWhich outcome occurs when a solenoid's turns are doubled?
A)Doubled magnetic energy density results✓
B)Halved magnetic field intensity
C)Quadrupled inductive time constant
D)Unchanged magnetic flux linkage
💡 Explanation
Doubling the turns doubles the magnetic field strength, due to self-inductance and increased current flow. Increases in magnetic field strength increase stored magnetic energy density via electromagnetic induction, because energy is proportional to the square of the field, therefore field density increases, rather than inductance changes.
