When engineers ask about electromagnetic relay types, Campus Component provides clear explanations and side-by-side comparisons. Induction types rely on eddy currents to rotate a disc or cup, while attraction types use direct magnetic pull on an armature or plunger. We emphasize trade-offs like response speed, contact life, sensitivity, and current capacity, so you can pick the relay ... https://www.campuscomponent.com/blogs/post/what-is-electromagnetic-relay-and-its-types
