If a magnetic field can form around any electrical appliance, are there large enough electric apparatuses that do form magnetic fields with strong enough force to affect persons or things nearby?
Then, how about an electromagnetic field? Or are they the same thing? Thanks.
MRI scanners use magnetic fields to realign your bodies molecules, anyone with metal implants might not be offered an MRI for safety reasons, ie MRI scanners can upset pacemakers, metal fillings, screws holding broken bones together etc. Some short term side effects are experienced by some people such as headaches dizziness nausea and fatigue.
An MRI scan works like what it says in this simple NHS link https://www.nhs.uk/c...ions/mri-scan/
Magnetic fields can be generated by electric, and yup electomagnetic fields are the result
Hope the link is not too long
