4. A total current I is distributed over the area between two cylinders with radii a and b as shown below. The actual distribution (or the current density) is unknown, but we know that it only depends on the radius p in the region between the two cylinders. The current density is zero outside this range (i.e., it is zero for p < a and p > b). The magnetic field in which region(s) is independent of p (regardless of the actual current distribution)? a. p < a and p> b b. p

Question
4. A total current I is distributed over the area between two cylinders with radii a and b as shown
below. The actual distribution (or the current density) is unknown, but we know that it only
depends on the radius p in the region between the two cylinders. The current density is zero
outside this range (i.e., it is zero for p < a and p> b). The magnetic field in which region(s) is
independent of p (regardless of the actual current distribution)?
a. p< a and p> b
b. p<a
c. everywhere
d. None of the three regions (i.e., magnetic field in each region may or may not depend on p
depending on the actual formula for the current density)
