Under the constitution what happens when conflicts arise between state and federal government?

When conflicts arise between state and federal government, according to the constitution, the Supremacy Clause and the Doctrine of Preemption come into play. According to the Supremacy Clause, the federal law is the supreme law, so a federal court may order a state to stop a behaviour or resolution that is in conflict or interferes with the interests of the federal law and government. In case of conflict, federal law prevails.
