PLEASE ANSWER ALL PARTS ASAP!!!!!!

1. A solenoid is 40 cm long, has a diameter of 3 cm, and is wound with 420 turns. If the current through
the windings is 5 A.
The magnetic field on the axis of a finite solenoid is given by
HONI
B=
2L
-(sin(0₂) - sin(0₁)), where ₁ and ₂ is shown in the figures below. Here, N is the total number
of turns in the solenoid of length L and I is the current through the solenoid. Note that 8, is
negative.
The goal of this question is to see how the magnetic field in a finite solenoid at different points
compares to an infinite solenoid.
Enter all answers to 4 significant figures.
