The code above sets up a ring of current $($or a loop of current$).$ To $$nd the magneticfield, the ring of current must be split into a number of little chunks. Which line of the code determines how many chunks to split the line into?

$$Tries $0/5$

$($b$)$ The while loop $($starting in Line $22)$ is there to determine the dl vector and location for each piece of the current loop. Which lines of code would you need to change in order for this while loop to work?

Select all that are True.

Line $22$

Line $23$

Line $24$

Line $26$

Line $27$

Line $28$
