Methods and systems are provided for expediting catalyst heating and cooling a braking system of a vehicle via applying a magnetic field to a vehicle system component. In one example, a method may include, responsive to a temperature of the catalyst being less than a threshold temperature, applying a magnetic field to an exhaust system component arranged proximate to the catalyst, and removing the magnetic field from the exhaust system component responsive to the temperature reaching the threshold temperature. In another example, the method further includes, following a vehicle braking event, applying the magnetic field to a braking system component, and removing the magnetic field from the braking system component responsive to magnetic field deactivating conditions being met.
