Magnetic assembly and assembling method thereof

The invention discloses a magnetic assembly and an assembling method thereof. The magnetic assembly at least comprises an iron core, a circuit board and a plurality of conductive elements, wherein the circuit board is provided with a plurality of conductive regions; each conductive element is provided with a first end part, a second end part and a connecting part for connecting the first end partand the second end part; the plurality of conductive elements are respectively arranged across the iron core; and the first end part and the second end part of each conductive element are respectively connected to the two adjacent conductive regions so that the plurality of conductive elements and the plurality of conductive regions form a plurality of numbers of rings on the iron core. The magnetic assembly and the assembling method thereof ensure that the plurality of conductive elements and the plurality of conductive regions form the plurality of numbers of rings on the iron core, and thenumbers of sensing rings f
