In long-wavelength moir´e patterns of homobilayer semiconductors, the layer pseudospin of elec-trons is subject to a sizable Zeeman field that is spatially modulated from the interlayer coupling in moir´e. By interference of this spatial modulation with a homogeneous but dynamically tunable component from out-of-plane electric field, we show that the spatial-temporal profile of the overall Zeeman field therefore features a topological texture that can be controlled in an ultrafast timescale by a terahertz field or an interlayer bias. Such dynamical modulation leads to the emergence of an in-plane electric field for low energy carriers, which is related to their real space Berry curvature – the moir´e magnetic field – through the Faraday’s law of induction. These emergent electromagnetic fields, having opposite signs at the time reversal pair of valleys, can be exploited to manipulate valley and spin in the moir´e landscape under the control by a bias pulse or a terahertz irradiation.
