In terms of physics, why is dust attracted to CD's after they are wiped with a dry cloth?
During the wiping process either electrons are transferred to the cloth from the CD or from the CD to the cloth. In either case the CD becomes charged. The charge produces an electric field which polarizes dust particles near it and the polarized dust particles are then attracted to the charged CD.kdkovach said:In terms of physics, why is dust attracted to CD's after they are wiped with a dry cloth?
Dust can stick to a CD after wiping it with a dry cloth due to static electricity. When the cloth rubs against the surface of the CD, it creates a static charge. This charge can attract dust particles, causing them to stick to the CD.
Yes, the type of cloth used can affect the amount of dust attracted to a CD. Materials that are more prone to creating static electricity, such as polyester or nylon, can result in more dust sticking to the CD compared to cotton or microfiber cloths.
Yes, using a damp cloth can help prevent dust from sticking to a CD. The moisture from the cloth can help neutralize the static charge on the CD, making it less attractive to dust particles.
Yes, wiping a CD in a circular motion can reduce the amount of dust attracted to it. This is because the circular motion helps evenly distribute the static charge on the surface of the CD, preventing a buildup of charge in one area where dust can easily cling to.
The frequency of wiping your CDs will depend on the environment they are stored in. If they are kept in a dusty or humid environment, it may be necessary to wipe them more often. Generally, wiping them once a week or every other week should suffice in preventing dust buildup.
