How do you demagnetize Styrofoam?
Styrofoam itself cannot be magnetized or demagnetized, as it is a non-magnetic insulating material. If you're trying to remove any static charge from Styrofoam, you can do so by grounding it or using a humid environment, as moisture can help dissipate static electricity. Additionally, rubbing it with a conductive material can also help neutralize any static charge.
What happen if after rubbing the glass rod with cloth and place it near a pieces of paper?
The glass rod will become charged and attract the paper due to static electricity. This is because rubbing the glass rod with cloth transfers electrons, giving the rod a negative charge. The paper, being neutral, will be attracted to the negatively charged rod.
Why rubber rod will attract small pellets of styrofoam?
A rubber rod can attract small pellets of styrofoam due to the process of static electricity. When the rubber rod is rubbed with a cloth or another material, it becomes negatively charged by gaining electrons. The styrofoam pellets, being neutral, can become polarized in the presence of the charged rubber rod, resulting in a temporary positive charge on the side closest to the rod. This attraction between the oppositely charged areas causes the styrofoam pellets to be drawn towards the rubber rod.
What kind of charge is the cloth left with when rubbed against perspex?
The cloth is left with a negative charge when rubbed against perspex due to transfer of electrons from the perspex to the cloth.
How do you purify air?
There are many ways to clean air purifiers. Typically, air purifiers can be cleaned by taking a soft and damp cloth and rubbing the whole air purifier with the cloth.
Will rubbing a silk cloth on glass cause electrons to move to the cloth?
Yes, rubbing a silk cloth on glass cause electrons to move to the cloth. As a result, glass rod acquires positive charge and silk acquires negative charge.
if you rub a plastic rod with a dry cloth what charge is left on the cloth?
The cloth will acquire a negative charge. Rubbing the plastic rod transfers electrons from the rod to the cloth, leaving the cloth with an excess of electrons, giving it a negative charge.
What is the overall electric charge on the ballon and on the cloth in the diagrtam?
The overall electric charge of the balloon is positive due to acquiring electrons when rubbed with the cloth. The overall electric charge of the cloth is negative because it loses electrons during the rubbing process.
When you rub a ruler with a cloth what happens to the cloth?
Rubbing a ruler with a cloth creates friction, which transfers some of the ruler's electrons to the cloth, giving the cloth a negative charge. This process is called triboelectrification.
What charge does a balloon have when rubbed by wool cloth?
A balloon becomes negatively charged when rubbed with wool cloth. This happens because the balloon gains electrons from the wool cloth during the rubbing process, giving it a net negative charge.
What is the sound of styrofoam rubbing against each other?
The sound of styrofoam rubbing against each other is often described as a squeaky or squeaking noise.

Additionally, rubbing it with a conductive material can also help neutralize any static charge.
How do you create static electricity with wool and styrofoam?
Rubbing a piece of wool fabric on a piece of styrofoam can create static electricity by transferring electrons between the two materials. As the wool gains electrons through friction, it becomes negatively charged, while the styrofoam loses electrons and becomes positively charged. This charge imbalance creates static electricity.
How can you charge copper rod by holding it and rubbing it?
By rubbing the copper rod with a cloth or your hands, you transfer electrons between the rod and the fabric through friction. This process creates a build-up of static charge on the surface of the rod, giving it a net positive or negative charge.
Why is it not possible to charge a metal rod held in hand by rubbing with cloth?
When a metal rod is held in hand, it gets grounded, which means the excess charge created on it during rubbing gets neutralized by the body's conducting properties. This prevents the accumulation of charge on the rod, making it unable to hold a charge.
Does rubbing a polythene rod with a duster take away positive charge from the cloth?
Rubbing a polythene rod with a duster can transfer electrons and create a charge imbalance (like triboelectric charging). If the polythene rod gains electrons during rubbing, it will become negatively charged, meaning the duster could potentially lose positive charge, but the overall charge conservation principle still applies.
If you rub a polythene rod with a cloth will it become magnetic?
Rubbing a polythene rod with a cloth will not make it magnetic. This process of rubbing generates static electricity, not magnetism. Magnetism is a property of certain materials, such as iron and cobalt, that have aligned magnetic domains, which is different from the electrostatic charge generated by rubbing polythene.
