The "powers that be at CentOS" have in their infinite "wisdom" decided
that developer stuff should go into one or more separate repositories.
Where you might find what you're looking for - if you're lucky. As
they've still not managed to publish all devel RPMs.

In fact the ImageMagick you're trying to install is served out of the
BlueOnyx YUM repository and isn't directly from CentOS.

Now if you look into /etc/yum.repos.d/ on your 5210R you'll see a couple
of repository files.

Most build dependencies and source packages are in the "PowerTools"
repo, which you need to enable in /etc/yum.repos.d/CentOS-PowerTools.repo

But fat dependencies such as ImageMagick *might* require dependencies
out of /etc/yum.repos.d/CentOS-centosplus.repo and
/etc/yum.repos.d/CentOS-Extras.repo as well.

So enable all three:

/etc/yum.repos.d/CentOS-centosplus.repo
/etc/yum.repos.d/CentOS-Extras.repo
/etc/yum.repos.d/CentOS-PowerTools.repo

But be sure to turn them off again when you're done installing whatever
you need.
