The kanji 旋 is a 形声文字 (keisei moji), which means it's a character formed by combining a semantic (meaning) component and a phonetic (sound) component. The left side is a radical called 方 (hō), originally depicted as a square. It then came to represent "direction" or "way". The right side is 㐱, which is a phonetic component, and is now simplified to 㐱 as well. Together, they combine to indicate circular motion or turning. The character evolution depicts the original meaning of this kanji.
