The invention provides a preparation method of an anti-surge amorphous and nanocrystalline magnetic core and the amorphous and nanocrystalline magnetic core, and relates to the technical field of magnetic core preparation, the preparation method comprises the following steps: S1, winding an amorphous and nanocrystalline strip to form a wound magnetic core; s2, putting the wound magnetic core into a container containing an insulating pressure-resistant solution, vacuumizing, applying pressure intensity, then taking out, baking and drying to obtain a dried magnetic core; and S3, the dried magnetic core is fed into a heat treatment furnace to be subjected to magnetic field heat treatment, and the anti-surge amorphous nanocrystalline magnetic core is obtained after the magnetic core is discharged out of the furnace. The amorphous nanocrystalline magnetic core has the advantages that breakdown voltage resistance of the magnetic core under high frequency is improved, magnetic loss of the magnetic core is reduced, t
