What are iron filings?
Q: What are iron filings?
A: Iron filings are small pieces of iron that resemble a dark gray powder.
Q: Where are iron filings commonly found?
A: Iron filings are a by-product of metalworking, so they are commonly found in metalworking facilities.
Q: What is the purpose of using iron filings in schools?
A: Iron filings are often used in schools to demonstrate magnetic field lines.
Q: How do iron filings behave when placed in a magnetic field?
A: When placed in a magnetic field, iron filings become small magnets and create chains parallel to the direction of the magnetic field.
Q: Why do iron filings become magnets in a magnetic field?
A: Iron filings become magnets in a magnetic field because iron is a ferromagnetic material and the south pole of each particle attracts the north poles of its neighbors.
Q: What is a ferromagnetic material?
A: A ferromagnetic material is a material that is attracted to a magnet and can become magnetized itself.
Q: How are iron filings useful in illustrating magnetic field lines?
A: Iron filings are useful in illustrating magnetic field lines because they line up in the direction of the magnetic field and create visible chains that demonstrate the path of the field.
