What is the difference between the earths magnetic field and a bar magnet?
The Earth's magnetic field is generated by the movement of molten iron in the outer core, while a bar magnet is a permanent magnet made of a material that can be magnetized, such as iron. The Earth's magnetic field is much weaker and more complex than that of a bar magnet, which has a consistent north and south pole.
What is the difference between soft and hard iron?
The essential difference between soft iron and hard iron is in the crystalline structure of the metals. This is sometimes due to the presence of impurities, but the over-riding effect is that of heat treatment. The basic techniques (for iron) are to get it white-hot, then cool it slowly; this produces soft iron. Alternatively, get it dull red, or bright red, or yellow, or white, then plunge it into cold liquid. This process, called quenching, hardens the iron. Picking the correct colour before quenching gives just the hardness needed.
What is a maganetic force explain with an example?
force that experience by ferromagnetic or paramagnetic substances when they are in the region of the magnetic field.For example, when you place a permenant magnet over an iron pin, the iron pin ( in this case, iron is ferromagnetic substances) is in the region of the magnetic field and attracted to the magnet.
When does a magnet affect another magnet something made of iron or a similar metal and moving charges?
A magnet affects another magnet, iron, or a similar metal through the interaction of their magnetic fields. Moving charges also create magnetic fields that can be influenced by a magnet's field. This interaction occurs when there is relative motion between the magnetic sources.
What to attract objects that contain iron?
You can attract objects that contain iron by using a magnet, as iron is a magnetic material. When you bring a magnet near objects containing iron, the magnetic force will cause them to be attracted to the magnet.
How do you tell the difference between silver and iron?
Silver is a shiny, white metal that is softer and more malleable than iron, which is a dull gray metal with a harder and more resistant structure. You can also use a magnet to distinguish between the two, as iron is magnetic whereas silver is not.
How can you tell the difference between a bar of iron a bar of copper and a magnet?
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
What is the difference between iron and magnet?
Iron is a chemical element that is a metal and is found in many everyday objects. A magnet is an object that produces a magnetic field and can attract iron and other materials with magnetic properties. So, while iron is a material, a magnet is a tool that uses magnetic properties to attract certain materials.
How would you separate copper strands and iron filings?
One way to separate copper strands and iron filings is by using a magnet. Copper is not magnetic but iron is, so you can use the magnet to attract and separate the iron filings from the copper strands. Alternatively, you could also use the difference in density between copper and iron to physically separate them using techniques like flotation or panning.
What is the difference between the earths magnetic field and a bar magnet?
The Earth's magnetic field is generated by the movement of molten iron in the outer core, while a bar magnet is a permanent magnet made of a material that can be magnetized, such as iron. The Earth's magnetic field is much weaker and more complex than that of a bar magnet, which has a consistent north and south pole.
Why does the magnet attract the iron?
the magnet attracts to iron by the magnetic field both the iron and the magnet have

Why does the magnet attract iron objects?
the magnet attracts to iron by the magnetic field both the iron and the magnet have
How do you seperate a mixture of iron filling and sawdust?
One way to separate a mixture of iron filings and sawdust is to use a magnet. The iron filings will be attracted to the magnet and can be easily separated from the sawdust. Alternatively, you can also use a sieve to separate the iron filings from the sawdust based on size difference.
What is the same between a magnet and an electromagnet?
They both attrack metal and they have iron in them
What material when placed between a magnet and iron best reduces the attraction?
A non-magnetic material, such as paper, plastic, or wood, would best reduce the attraction between a magnet and iron. These materials do not interact strongly with magnetic fields, so they will create a barrier that decreases the magnetic force between the magnet and the iron.
Does a magnet attract iron?
Yes, a magnet will attract iron. This is because iron is a type of magnetic substance, and the magnet can penetrate it to increase the magnetic field and draw it near it.
