Question

In the example calculation involving a solenoid and a larger coil placed around it, the magnetic flux (ΦB) that determines the induced EMF in the coil is calculated using the magnetic field that exists within which specific region?
Options
A The entire area of the larger coil.
B Only the cross-sectional area of the solenoid.
Correct Answer
C The region outside both the coil and the solenoid.
D The average area between the solenoid and the coil.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Slide 25 explicitly notes: 'Only field in coil is inside solenoid'. This means the magnetic field created by the solenoid is essentially confined to its interior, and thus the flux through any larger coaxial coil is determined by the field within the solenoid's cross-sectional area.

Hint

Pay close attention to the specific note given in the example problem setup.
