▎ 摘　　要

NOVELTY - A magnetron fluid motion power generation device comprises a hollow tubular casing and magnetic droplets loaded in the casing, where the casing is a graphene tube, the graphene tube outer surface is coated with polymethyl methacrylate and the magnetic droplets are a suspension of tri-iron tetroxide. USE - Magnetron fluid motion power generation device. ADVANTAGE - The device has excellent controllability due to the introduction of the ferroferric oxide magnetic droplets, changes the direction of the output voltage by changing the moving direction of the magnet and can be reused multiple times. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for fabricating a magnetron fluid power generation device, which involves growing a continuous graphene film on the surface of the copper wire substrate by chemical vapor deposition, coating the surface of the obtained graphene film with a polymethyl methacrylate solution, drying, removing the copper wire substrate by solution etching to obtain a polymethyl methacrylate-supported hollow graphite alkene shell, injecting a suspension of ferroferric oxide by a pipette into the obtained graphene tube shell, extracting the copper wire at both ends of the graphene tube shell with silver glue to obtain the magnetron fluid power generation device.
