The present invention discloses a magnetic assembly which comprises a magnetic element and a magnetic conductive element. The magnetic element is provided with two ends of different electrodes and is internally provided with an axial through-groove, and magnetic fields circling around in different directions are formed in the interior and the exterior of the magnetic element. The magnetic conductive element is a sheet bar provided with an end fitted on the magnetic element, a protruding column sleeved into the through-groove of the magnetic element is arranged on the sheet bar, and magnetic field encircling paths of the magnetic element is concentrated through the guidance of the sheet bar and the protruding column of the magnetic conductive element, i.e., magnetic flow concentration regions can be generated between the magnetic element and the magnetic conductive element. Therefore, with the combination of the magnetic element and the magnetic conductive element, magnetic flux density of the magnetic assembly at a local area can be greatly raised, so as to enhance magnetic field strength of the magnetic assembly, thereby achieving practical benefits of strengthening magnetic force and saving magnetic materials.
