What event creates and sustains natural electromagnetic fields? And what do they mean when they say a photon mediates the electromagnetic field?

Natural electromagnetic fields are generated by natural phenomena such as lightning, the Earth's magnetic field, and the sun's radiation. These fields are also produced by living organisms, such as the human brain and heart.
Natural electromagnetic fields can have both positive and negative effects on living organisms, depending on the strength and frequency of the field. For example, the Earth's magnetic field helps guide animal migration and plays a role in the human body's circadian rhythm. However, exposure to high levels of electromagnetic fields can also have adverse health effects, such as increased risk of cancer.
Yes, natural electromagnetic fields can be measured using specialized equipment such as magnetometers and electromagnetic field meters. These instruments can detect the strength and frequency of the field, as well as any changes over time.
The strength of natural electromagnetic fields can be influenced by a variety of factors, including the distance from the source, the type of source, and the surrounding environment. For example, the strength of the Earth's magnetic field is stronger near the poles and weaker near the equator.
Natural electromagnetic fields have many practical applications in everyday life. They are used in navigation systems, communication devices, and medical equipment such as MRI machines. They are also harnessed for renewable energy sources, such as wind turbines and hydroelectric power plants.
