- ‘Base stations are surrounded by electromagnetic fields, an energy force that is created when electricity is generated.’
- ‘All fields - in particular electromagnetic fields - have fluctuations.’
- ‘Exposure to electromagnetic fields, such as magnetic resonance imaging, are contraindicated.’
- ‘The electromagnetic field does not carry charge and hence photons do not interact with each other.’
- ‘Tears form in the Earth's electromagnetic field, letting massive amounts of UV rays in - melting cars, bridges, and people.’
