I've always found the "tuning" process involved with small magnetic loop antennas to be somewhat tedious.  These antennas are very sensitive to small changes in frequency and adjustments can be a bit taxing.  But, thanks to this excellent, informative video from Johnny of "Signal Search", the tuning process can become easier and less stressful. In this video, Johnny uses a magnetic loop design by W4OP.  As with many magnetic loop antennas, adjustment of the coupling loop is vital to precise tuning.  With a little time and effort, small magnetic loop antennas can become viable options for those operating in deed-restricted homes or apartments.

An excellent, informative video tutorial on how to tune a magnetic loop antenna. In this case, the mag loop is the LNR Precision Loop, which has a tuning control built in at the base of the loop.  This loop is based on a design by W4OP.  This mag loop allows adjustments of the coupling loop which is critical for magnetic loop antenna design.
