If you're new to video editing, the Magnetic Timeline might seem great for editing, and it is, most of the time. However, there's a reason that the Position tool exists. If you're not careful, the Magnetic Timeline can mess up the sync and timing of your project. Perhaps halfway through your project, you have a song where you've cut a series of clips to the beat. If you moved one clip out to an earlier portion of your project before the song starts, it could throw the whole pacing of the edit off! You might want to turn on the Position tool (that is turn the Magnetic Timeline off) to prevent this sort of issue.

When you delete clips using the Magnetic Timeline, all clips following the deleted clip ripple back to fill the gap. This may seem great at first, but be careful! Depending on the complexity of your sequence, this can push certain elements you may have carefully lined up out of sync, such as narration or clips cut in beat with music. To delete a clip, but leave behind a gap clip, highlight the clip you want to remove and hit Shift + Delete (also known as the "big" Delete key on full external keyboards—you can simply hit the small Delete key on full-size keyboards). This ensures nothing is accidentally moved out of sync later in your project.
