ELI5. What does it mean for magnetic field to have sound?
- 1970-01-01 4y agoRead the 2nd sentence of the article, and you'll get it.
- CoastalCoder 4y agoIMHO the 2nd sentence is still pretty vague and maybe misleading. IIUC, they took a model of earth's magnetic field over the past 100,000 years, fed it into (some magic box that the article doesn't explain), and turned it into a public art exhibit.
- queuebert 4y agoOne simple answer is that electricity run through a loudspeaker makes sound. And physics tells us that changing magnetic fields cause electricity. You could run that electricity through a speaker and "hear" the Earth's changing magnetic field. You would necessarily have to speed it up because we don't have 20,000 years to listen.
