A good example of electronic devices not being electromagnetically compatible are speakers and cellular phones. When a phone is set next to a speaker, it does not react because the EM wave emissions are minimal, but when there is an incoming call or message the EM waves emitted are stronger and these are caught in the speaker&#8217;s coils, generating electricity that makes the speaker produce static sound.\n<\/p>\n<p>Electromagnetic interference can cause damaging effects to various technologies, which is why electromagnetic compatibility aims to control this interference in order to mitigate risk of equipment damage.\n<\/p>\n<p>Disciplines related to the promotion of electromagnetic compatibility and control of electromagnetic interference include:\n<\/p>\n<ul>\n<li>Threat characterization \u2013 Finding relevant EM emission threats<\/li>\n<li>Setting of standards for emission and vulnerability levels \u2013 Standardizing what level of emissions are acceptable<\/li>\n<li>Designing for standard compliance \u2013 Designing a standard for designers and manufacturers to comply to<\/li>\n<li>Testing for standard compliance \u2013 Testing the designs for compliance and adherence to standards<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>What Does Electromagnetic Compatibility Mean?
