Topological magnetic charge  Q  is a fundamental parameter that describes the magnetic domains and determines their intriguing electromagnetic properties. The ability to switch  Q  in a controlled way by electrical methods allows for flexible manipulation of electromagnetic behavior in future spintronic devices. Here, the room‐temperature current‐controlled topological magnetic transformations between  Q  = −1 skyrmions and  Q  = 0 stripes or type‐II bubbles in a kagome crystal Fe 3 Sn 2  are reported. It is shown that reproducible and reversible skyrmion–bubble and skyrmion–stripe transformations can be achieved by tuning the density of nanosecond pulsed current of the order of ≈10 10  A m −2 . Further numerical simulations suggest that spin‐transfer torque combined with Joule thermal heating effects determine the current‐induced topological magnetic transformations.
