Press and hold the "Shift" and the "Ctrl" keys on your key board and press the "+" key to increase the magnification of your artwork. If the area you are selecting with the "magic wand" is small, then you should increase the size of the image to make it easier to work on.
Click the area on which you want to work with the "magic wand." You will notice the selected area will have a moving dotted line around it. If the selection is complete, then you can proceed and edit the selection the way you want. If you need to add or subtract from the selection, right-click your mouse and you will a see a "green wand" and "red wand" option appear. The "green wand" will allow you to add to your selection. The "red wand" will allow to remove parts of the image from your selection.
