What is fringing of electric and magnetic fields? What is the physics behind it?

In summary, fringing of electric and magnetic fields occurs when the field lines near the edges of conducting bodies deviate from their expected paths due to the interaction between charges or currents on the bodies and external fields. This phenomenon is significant in the design and operation of electrical and magnetic systems and can be controlled or minimized through careful design and placement of conducting bodies. Understanding fringing is important in gaining a better understanding of the fundamental principles of electromagnetism.

I want to know what exactly is magnetic and electric field fringing and what is the cause of it?

you have a fringing field around the edge of a parallel plate capacitor
because the plates are not infinite. If the plates were infinite the E field lines would go straight across to the other plate.
from far away it kind of looks like an electric dipole.
 

1. What is fringing of electric and magnetic fields?

Fringing of electric and magnetic fields refers to the phenomenon in which the field lines near the edges of conducting bodies deviate from their expected paths. This occurs due to the presence of charges or currents on these bodies.

2. How does fringing of electric and magnetic fields occur?

The fringing of electric and magnetic fields is a result of the interaction between the charges or currents on the conducting bodies and the external electric and magnetic fields. This interaction causes the field lines to bend and deviate near the edges of the bodies.

3. What is the significance of fringing in electrical and magnetic systems?

Fringing of electric and magnetic fields is important in the design and analysis of electrical and magnetic systems. It can affect the performance and efficiency of these systems and must be taken into account during their design and operation.

4. Can fringing be controlled or minimized?

Yes, the effects of fringing can be controlled or minimized through careful design and placement of conducting bodies in electrical and magnetic systems. This can involve shaping the bodies to reduce edge effects or using shielding materials to redirect the field lines.

5. How does fringing relate to the overall understanding of electromagnetism?

Fringing of electric and magnetic fields is a result of the fundamental principles of electromagnetism, such as Coulomb's law and Ampere's law. Understanding fringing helps us better understand and analyze the behavior of electric and magnetic fields in various systems and applications.
