The static and dynamic magnetic properties of Artificial Spin Ices (ASIs) are typically investigated in zero magnetic field. However, magnetic fields can provide a versatile tuning parameter, by driving phase transitions between different magnetic orders, or tuning through regimes where quasiparticle excitations (e.g., ``magnetic monopoles'') can readily form and proliferate. Here, using simulations supported by noise experiments, the authors map out the equilibrium thermodynamic properties and magnetic phases of square and quadrupolar ASIs as a function of applied in-plane magnetic fields.
