Note that 'ls' doesn't see this pattern at all. The pattern is expanded
by the shell to all existing files matching the pattern. This list of
files is then passed to ls. Using 'echo' would yield (almost) the same
result in this case.

I think you meant to write
for MAGFILE in `ls $MAGDIR/*.[Zz][Ii][Pp]`
instead. What is happening with your version is the following:
- the shell tries to find files matching your pattern in the current
directory
- since there is no file matching your pattern, it leaves the pattern
unchanged
- $MAGDIR is expanded
- the unexpanded pattern and the content of $MAGDIR are passes to 'ls'
- 'ls' prints an error message for your pattern and lists the content of
$MAGDIR
Another hint: you don't need 'ls' for your case at all. 'ls' without any
parameter just prints out the names of the files that have been passed
to it by the shell. You can get away without the command substitution:
for MAGFILE in $MAGDIR/*.[Zz][Ii][Pp]
# …
done
