Is kitchen wrap adhesive because of Electric Charge?

AI Thread Summary
Kitchen wrap, often referred to as cling film, adheres to surfaces due to electrostatic charges. The discussion clarifies that the stickiness is not related to metallic foil but rather to the properties of the plastic film itself. Participants emphasize the importance of terminology, distinguishing between foil and film. The adhesive quality is attributed to the film's interaction with positively charged materials. Overall, the conversation highlights the scientific basis behind the clinginess of kitchen wrap.

Hello,

I just came across this question and no answer could be find, my best assumption is that kitchen foil is simply 'holding' into positveley charged materials?

Thanks,
JJ

Thanks, I was right :cool:
 
N.B. It's not "foil". Foil is the terms for thin metal (a conductor). It's Film, we're discussing.

it's all clingon to me :biggrin:
 
Thread 'Inducing EMF Through a Coil: Understanding Flux'
Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.
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 ...
