Movement by electrical induction

AI Thread Summary
When a charged object is brought near a neutral soda can, the can experiences polarization, resulting in a positive side and a negative side. This polarization causes the can to be attracted to the charged object, as the opposite charges attract. A negatively charged object repels electrons in the can, creating a positive charge on the side closest to it, which enhances the attraction. Induction is not only interesting but also practical, as it is utilized in devices like dust extractors that attract neutral particles. Overall, electrical induction effectively demonstrates how charge distribution influences movement and attraction.

So, when you bring a charged object near for example a soda can, I get that the soda can gains a positive side and a negative side, but the can also moves towards the charged object, why is that?

Is it because if you put a negative charged object near the soda can the side of the can nearest to the object gains a positive side because the electrons are repulsed, and the negative object attracts the positive side of the can?

Thanks in advance

Okay, pretty interesting that induction makes an object have an electric charge on the one hand, and attracts it aswell. Thank you very much!
 
Induction is very handy in things like dust extractors which attract electrically neutral dust particles. Much more use than picking up bits of paper with a comb.:wink:
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
