A magnetic assembly (100a, 100b, 100c, 100d, 100e, 100f, 200a, 200b, 200c, 200d, 200e, 200f) includes a first magnetic core (110a, 110c, 210a, 210b, 210c, 210d, 210e, 210f), a second magnetic core (120a, 120d, 220a, 220b, 220c, 220d, 220e, 220f), at least one circuit board (130, 230), and multiple pillars (140a, 140b, 140c, 140d, 140e, 140f). The second magnetic core (120a, 120d, 220a, 220b, 220c, 220d, 220e, 220f) and the first magnetic core (110a, 110c, 210a, 210b, 210c, 210d, 210e, 210f) are assembled with each other to define an internal space (S1, S2). The circuit board (130, 230) is disposed in the internal space (S1, S2). The circuit board (130, 230) has multiple through holes (132, 232) separated from each other. The pillars (140a, 140b, 140c, 140d, 140e, 140f) are located in the internal space (S1, S2) and respectively correspond to the through holes (132, 232) passing through the circuit board (130, 230), and multiple air gaps (A1, A2, A3, A4, B1, B2) are formed between the pillars (140a, 140b, 140c, 140d, 140e, 140f) or between the pillars (140a, 140b, 140c, 140d, 140e, 140f) and at least one of the first magnetic core (110a, 110c, 210a, 210b, 210c, 210d, 210e, 210f) and the second magnetic core (120a, 120d, 220a, 220b, 220c, 220d, 220e, 220f).
