    Dielectric Sphere
AI Thread Summary
A dielectric sphere is defined as a sphere made from a dielectric material, which is an electrically insulating substance that enhances capacitance in applications like capacitors. In the context of optical tweezers, dielectric spheres can be manipulated using focused laser beams due to their interaction with light. The discussion highlights confusion around the term and its relevance in optical trapping techniques. Understanding the properties of dielectric materials is crucial for their application in optical tweezers. This knowledge is essential for utilizing dielectric spheres effectively in scientific research.

im confused about what a dielectric sphere is. I have tried googleing it but i couldn't find anything that useful, please help
 
Physics news on Phys.org
It's a sphere made of a dielectric material. A "dielectric" is a (usually) electrically insulating material such as you put between the plates of a capacitor in order to increase the capacitance.

What is the context of your question?

it is in relation to optical tweezers, i read on wikipedia that they can be used for things such as a dielectric sphere.
 

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
