A ''portative electromagnet'' is one designed to just hold material in place; an example is a lifting magnet. A ''tractive electromagnet'' applies a force and moves something.<ref name="Marks 105">{{cite book |first=Chester L. |last=Dawes |chapter=Electrical Engineering |title=Standard Handbook for Mechanical Engineers |edition=7th |editor-first=Theodore |editor-last=Baumeister |publisher=McGraw-Hill |date=1967 |page=15-105<!-- hyphenated pages! -->}}</ref>

Electromagnets are very widely used in electric and [[electromechanical]] devices, including:
* [[electric motor|Motors]] and [[Electric generator|generators]]
* [[Transformer]]s
* [[Relay]]s
* [[Electric bell]]s and buzzers
* [[Loudspeaker]]s and [[headphone]]s
* [[Actuator]]s such as valves
* [[Magnetic recording]] and data storage equipment: [[tape recorder]]s, [[VCR]]s, [[hard disk]]s
* [[MRI]] machines
* Scientific equipment such as [[mass spectrometer]]s
* [[Particle accelerator]]s
* [[Magnetic lock]]s
* [[Magnetic separation]] equipment used for separating magnetic from nonmagnetic material; for example, separating ferrous metal in scrap
* Industrial lifting magnets
* [[Magnetic levitation]], used in [[maglev train|maglev trains]]
* [[Induction heating]] for cooking, manufacturing, and [[hyperthermia therapy]]
