Drakkith said:Consider that two electrically charged particles will experience a force due to their charges no matter what the distance is between them
Intropersona said:Can you please explain simply why that is so?
Drakkith said:It's an observed fact. Charged particles are observed to either repel or attract each other. The strength of the force follows the inverse square law, which I gave above. What would you like explained?
Intropersona said:That doesn't tell me much about why the forces of each atom are linked?
Drakkith said:You won't find an absolute answer. We know how to calculate the strength of the force, but we don't know the fundamental cause of the EM force or any of the other fundamental forces.
Intropersona said:Well, that seems quite a predicament for the cosmic evolution of human beings now isn't it. If we were to know... what could we do with that knowledge?
Electromagnetic fields exist everywhere in space, even in areas where there is no matter. This is because electromagnetic fields are created by the movement of electrically charged particles, such as electrons. These particles can move freely through space, creating electromagnetic fields even in the absence of matter.
Electromagnetic fields exist in a vacuum because they are a fundamental property of space. In the absence of matter, the fabric of space itself can still be affected by electromagnetic fields. This is because electromagnetic fields are made up of electric and magnetic fields that interact with each other and can propagate through space.
Yes, electromagnetic fields can exist in a perfect vacuum. In fact, a perfect vacuum is the ideal environment for electromagnetic fields to exist, as there are no particles to disrupt the movement of electrically charged particles that create the fields.
Electromagnetic fields exist in the absence of matter because they are a fundamental property of the universe. They do not require matter to exist, but instead are created and sustained by the movement of electrically charged particles and the interactions between electric and magnetic fields.
Yes, there are many practical applications for electromagnetic fields in the absence of matter. For example, electromagnetic waves can travel through space to transmit information in the form of radio, television, and cell phone signals. Additionally, electromagnetic fields are used in technologies such as MRI machines, particle accelerators, and radio telescopes.
