Why is iron powder magnetic?
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
Is ZnO magnetic?
ZnO , chemically called zinc oxide is not magnetic at all.It is a white powder used in various small industries , like electro plating, as a filler in various application.
Would a screen be useful for separating a mixture of gravel and diatomaceous - earth powder?
yes it would. you could also separate it with a magnet then the gravel would stick to the magnet. +++ Magnetic gravel? You can separate diatomaceous earth from gravel simply by sieving. Gravel is not magnetic (unless it happens to be a magnetic ore of iron!).
How do you make homemade magnetic powder?
I may not be remembering the details of this correctly; so somebody please correct me if I'm wrong. I did this experiment in elementary school: 1. Oxidize steel wool using a vinegar solution (inferring vinegar from unsuccessful Google search for this experiment, but it sounds right.) 2. Heat the resulting red oxide powder The resulting black colored powder should be responsive to magnetic fields. This experiment is detailed in a 1983 - 1985 World Book Encyclopedia if memory serves.
Is sulfur magnetic or non magnetic?
Not magnetic
Why is iron powder magnetic?

Is talcum powder magnetic?
No. Talcum power is not magnetic.
What is the magnetic permeability values of En8 steel and iron powder?
what is magnetic ppermeability of EN8
What materials could you use to see the fields around a magnet?
Magnetic powder, iron powder, etc.Iron Filings.
What materials could you use to see the field lines around a magnet?
Magnetic powder, iron powder, etc.Iron Filings.
How do you separate talcum powder and sugar?
use a kitchen strainer and pour water over the talcum powder nail mixture use a magnet talcum powder is non magnetic
Why did powder did not reacted with magnet?
It's probably not metal. Most metals are magnetic but some aren't.
What is the composition of laser toner?
laser toner consist of : developer drum - where the powder toner gets cooked magnetic roller - where the powder toner gets charged then sticks and gets applied to drum pcr - this is a roller right below the drum this is to secure the paper into the drum toner hopper - where powder toner is stored and here is where magnetic roller pulls toner waste toner hopper - where CHARGED powder toners goes

What did the Chinese invent during the Golden Age that enabled them to have many books and libraries?
gun powder and magnetic compasses
Is there a simple test to distinguish between aluminum powder and zinc powder?
Use an externally magetic field: Zinc is diamagnetic and Aluminum is paramagnetic. Paramagnetism (Aluminum) is a form of magnetism whereby certain materials are attracted by an externally applied magnetic field. In contrast with this behavior, diamagnetic materials (Zinc) are repelled by magnetic fields.
How can you see the magentic field formed around wires containig electricity?
Place a cardboard along the cross-section of wire and hold the cardboard horizontally and put iron powder on it and pass current through the wire...the powder will align itself in shape of magnetic field. Another method you can try is on cardboard place a magnetic compass and the needle will align itself in the path of magnetic field and keep marking the position of needle.
