Micromagnets with collinear electric and magnetic dipole moments are embedded in a polymer to form a magnetic composite (see image). Each particle is a micromagnet that sits in a fluid‐filled cavity in which it is free to rotate. Under the application of a voltage, the multifunctional particles align with the applied electrostatic field to give rise to a net magnetization.
