Playing B7: what goes wrong

B7 leads to E

B7 is the V7 chord of E major: its D♯ and A pull to E and G♯. Songs in E minor use B7 the same way (the major V borrowed from the harmonic minor scale), so Em, B7, Em is a very common change.

Let the open B ring

String 2 is open in this shape. The ring finger on string 3 fret 2 and the pinky on string 1 fret 2 both lean toward it: arch them so the open B sounds.
