Which chemical application on copper plate to repel iron needle?
To repel an iron needle or to create a repulsive effect on iron, you would typically use a strong magnet of opposite polarity. However, if you are specifically asking about a chemical that can repel iron or create a non-magnetic repulsion, there isn’t a chemical that inherently repels iron directly.
Most interactions with iron are due to magnetic or chemical properties, such as oxidation or corrosion. For non-magnetic repulsion, other physical means like electrostatic forces can be used, but these involve electric charges rather than chemical substances.
If you are looking for a way to protect iron from rusting or corrosion (which is a form of repulsion in terms of preventing chemical reactions with the environment), substances like oil, paint, or galvanization (coating with zinc) are commonly used.

chemical application on copper plate to repel iron needle
If you want to apply a chemical to a copper plate to repel an iron needle, you will need to use a method that prevents direct contact or creates a barrier. Here are a few approaches:
Non-Stick Coatings: Applying a non-stick coating, such as Teflon (polytetrafluoroethylene, PTFE), can make the copper surface slippery and reduce friction, causing the iron needle to slide off or be repelled.
Lubricants: Using a lubricant like silicone spray or grease can create a slippery surface on the copper plate, which would prevent the iron needle from sticking to it.
Electrostatic Repulsion: Applying a static charge to the copper plate can create an electrostatic field. If the iron needle is also charged with the same polarity, it will be repelled. This method requires careful handling of static electricity and insulating materials.
Electromagnetic Fields: Embedding an electromagnet beneath the copper plate and generating an alternating magnetic field can create a repulsive effect on the iron needle. This is more complex and requires electrical setup.
Chemical Coatings: Applying a chemical coating that interacts with iron to form a repellent layer. For example, a thin layer of oil or wax can be applied to the copper plate, creating a barrier that reduces direct contact with the iron needle.
For practical purposes, non-stick coatings or lubricants are the simplest and most effective methods to create a repellent effect between a copper plate and an iron needle.
