How do you test whether a plastic rod that has been given an electric charge would attract or repel a magnet?

The charged plastic rod has affinity for insulting items. So, things like saw dust, paper pieces get attracted to it. You can try giving some opposite charge to the magnet. That way it can get attracted to the charged rod.

How could you test whether a plastic rod that has been given an electric charge?

If you rub a glass rod with a cloth, the charge produced on the glass rod is called positive, whereas when a plastic rod is rubbed with a cloth, the charge produced on the plastic rod is negative.

How will you test whether a rod is a magnet or not?

To test if a given rod is made of iron or not, we need to bring it near a magnet. If the rod is attracted to the magnet, it’ll prove that the rod is made of iron. It is Sitting Duck magnet.

Can a charged plastic rod attract a magnet?

I thought that because the charge on the rod is static, there wouldn’t be an interaction with the magnetic field, however the answer to the question states that both poles of the magnet would attract the rod. A positively, electrically charged rod is brought near a permanent magnet.

Would a charged plastic rod attract or repel a magnet?

If a negatively charged plastic rod is brought near to another negatively charged rod, the rods will move apart as they repel each other. If a positively charged rod is brought close to a negatively charged rod, the rods will pull together as they attract each other.

What happens when a plastic rod is rubbed with a dry cloth?

When a plastic rod is rubbed with a cloth, the plastic rod becomes negatively charged as electrons from the cloth are deposited on the plastic rod.

How does a plastic rod become positively charged?

For example, when a plastic rod is rubbed with a duster, electrons are transferred from one material to the other. The material that loses electrons becomes positively charged. The duster picks up electrons from the rod. This leaves the rod with a positive overall charge and the duster with a negative overall charge.

How can we determine if an object is charged or not?

In order to tell the sign of an object charge, you need another object with a known positive or negative charge. If you rub a piece of glass with silk, it will have a positive charge (by convention). If you rub a piece of amber with fur, it will have a negative charge (also by convention). Use whatever you have handy.

How will you test whether a given rod is a made of iron or copper?

The simple test to See whether a rod is off iron or Copper, Bring a horseshoe Magnet near to it and if the rod gets atrracted to it, it means it,s of iron.

How do you test if an object is a magnet?

One way to be sure that your test piece material isn’t magnetic is if it’s a wire. Moving a permanent magnet around a loop of wire will induce a voltage around that loop which can be read with a galvanometer (or any sensitive voltmeter) — this takes advantage of Faraday’s law of Induction.
