The magnetic component of electromagnetism

In summary, a magnetic field can exist without electricity, as shown by lodestone. However, electricity and magnetism are closely connected and cannot exist without each other. In a vacuum, knowing the properties of one component of electromagnetism can give you information about the other, but in materials this is not always the case.

May a magnetic field exist w/o electricity? Yes, as lodestone shows us but where is the electricity? Electricity generates magnetism with it. So where is the electricity with lodestone?

Also, if the wavelength of the electromagnetic standing wave yields a particular characteristic frequency(HZ), does this characterize both the electrical and the magnetic component? In other words, do we ascribe Hz to the magnetic component and use that to characterize the magnetic field created?

You can have magnetism without electricity, but you won't find magnetism without an electric field. They're attached at the hip.

In a vacuum knowing the properties of one or the other component of electromagnetism tells you what you need to know about the other, though you need more than the frequency to do it. In materials, not so much. (Edit: Unless you know everything you need to know about the material, I suppose.)
 

FAQ: The magnetic component of electromagnetism

1. What is the magnetic component of electromagnetism?

The magnetic component of electromagnetism is one of the fundamental forces of nature. It is responsible for the interaction between electrically charged particles in motion, creating a magnetic field.

2. How does the magnetic component of electromagnetism work?

The magnetic component of electromagnetism is created by the movement of electric charges. When an electric current flows through a wire, it creates a magnetic field around the wire. This field can interact with other electrically charged particles, creating forces and causing objects to move.

3. What are some real-world applications of the magnetic component of electromagnetism?

The magnetic component of electromagnetism has many practical applications, such as in motors and generators, where it is used to convert electrical energy into mechanical energy. It is also used in MRI machines, particle accelerators, and many other devices.

4. How does the strength of the magnetic component of electromagnetism change with distance?

The strength of the magnetic component of electromagnetism follows an inverse square law, meaning that it decreases in strength as the distance from the source increases. This is why magnets become weaker the further away they are from each other.

5. How does the magnetic component of electromagnetism affect the behavior of light?

The magnetic component of electromagnetism plays a crucial role in the behavior of light. Light is an electromagnetic wave, meaning it has both electric and magnetic components. The interaction between these components determines the properties of light, such as its wavelength, polarization, and speed.
