# Why Do Opposite Charges Result from Induction?

• jackdamack10
In summary, when a positively charged rod is brought near a neutral rod, induction occurs which causes the neutral rod to have opposite charges. When the charged rod touches the neutral rod, conduction takes place and a transfer in charge occurs. This is because the positively charged rod repels the positive charges of the neutral rod, causing the unlike charges to be closer together and the like charges to be further apart. This effect is called polarization in a nonconduction rod.

Induction --> Positively Charged rod is brought near neutral rod.
Conduction --> Charged rod touches the neutral rod creating a transfer in charge

What I don't understand is that why "Induction" causes the two rods to have opposite charges. Is it because the positively charge rod repels the positive charges of the neutral rod and attracks the negative charge?

thanks

Yes to your thoughts on induction. The neutral rod remains neutral, but the average distance between "like charges" is greater than the average distance for the "unlike charges". In a nonconduction rod, the effect is called polarization. The individual mollecules become polarized with the like charges a bit farther away from the charged rod than the unlike charges.

Your understanding is correct. Induction occurs when a charged object is brought near a neutral object, causing the electrons in the neutral object to shift and create a separation of charges. In this case, the positively charged rod repels the positive charges in the neutral rod, causing them to move away from the charged rod. This leaves the neutral rod with a net negative charge, as the positive charges have moved away. This is why the two rods end up with opposite charges after induction.

## 1. What is the process of induction in science?

Induction is a method of reasoning that involves observing a specific set of data or evidence and using it to make a general conclusion or prediction. This process involves making a hypothesis based on the observed data and then testing that hypothesis through further experiments or observations.

## 2. How does induction differ from deduction?

Deduction is a method of reasoning that involves starting with a general principle or theory and using it to make specific predictions or conclusions. In contrast, induction starts with specific observations and uses them to make a general conclusion or prediction.

## 3. What are some examples of induction in science?

Examples of induction in science include the process of developing a theory based on observed data, such as Darwin's theory of evolution based on his observations of different species, or the discovery of gravity based on observations of objects falling to the ground.

## 4. How is induction used in the scientific method?

Induction is an important part of the scientific method, as it allows scientists to make general conclusions or predictions based on specific observations. After a hypothesis is formed through induction, it is then tested through experiments or further observations to determine its validity.

## 5. What are the limitations of induction in science?

One limitation of induction is that it can lead to false conclusions if the observed data is not representative of the entire population or if there are underlying factors that are not accounted for. Additionally, induction alone cannot prove causation, as there may be other factors at play that are not being observed. Therefore, it is important for scientists to use a combination of induction and deduction in their reasoning to ensure accurate conclusions.
