Consider the loop of wire shown below:
The loop consists of two circular arcs with smaller radius R1 and
larger radius R2 connected by two straight, radial
segments.
a) Find the magnetic field at the point P. How would your answer
change if we reversed the direction of the current?
b) What is the magnetic dipole moment of the loop?
c) Now suppose φ0 = 2π. What is your magnetic field from part a) in
this case? Compare your answer to the magnetic
field due to a loop of wire at the very center of the loop.

4. Consider the loop of wire shown below: The loop consists of two circular arcs with smaller radius R1 and larger radius R2 connected by two straight, radial segments. a) Find the magnetic field at the point P. How would your answer change if we reversed the direction of the current? b) What is the magnetic dipole moment of the loop? c) Now suppose 0o = 27. What is your magnetic field from part a) in this case? Compare your answer to the magnetic field due to a loop of wire at the very center of the loop.
