What else can I help you with?
How do you find the shape of a magnetic field using a compass?
Yes. I can be done using iron filings and a clear piece of plastic. Pour on the iron filings, put on the plastic, and then the magnet. The iron filings should form the shape of the magnetic field around it. If that does not work, here is a link to a picture... http://www.fi.edu/htlc/teachers/lettieri/magneticfields.jpg Hope that helps.
What are the metals that is not magnetic?
4 metals are not magnetic 1. Aluminium 2. Gold 3. Copper 4. Brass these metals can only be magnetised by very scientific work which i cannot understand 5. don't forget silver...
Why doesn't iron act like a magnet?
Great question. The Earth has a magnetic field but it is not strong enough to overcome the other forces affecting pieces of iron. But if you wanted to make a super-accurate weighing scale, you would avoid iron for its hanging parts. And every steel can in your kitchen is magnetized from sitting in the Earths magnetic field. Put a compass needle close to a can of beans and see!
Objects that are attracted to magnets contain what types of metal?
Iron (or, from a physics standpoint, ferrous or, more probably, ferromagnetic metal). Magnets attract magnetic material, and there are only a few ferrous materials around. The word ferrous is from the word ferrum, which is the Latin word for iron. The chemical symbol for iron is Fe and it comes from the same source. Iron, cobalt and nickel are the "big three" ferromagnetic materials, but gadolinium and dysprosium also exhibit ferromagnetic properties. Certainly compounds and mixtures that include these elements are (usually) ferromagnetic. Wikipedia has some good info posted in their article on ferromagnetism. Need a link? You got it.
Why does the compass rose point north?
it doesn't, it points to Magnetic North which is somewhere in the north of Canada. A compass may point 20 degrees or more different from geographic north. The North pole of a magnet will point to magnetic north. The next question is why is the Earth magnetic, and why does it have a south pole magnetic near the North pole. I haven't seen a really good explanation. Something to do with the centre of the Earth having a layer of liquid iron that is rotating, and moving conductors generating a magnetic field. The Earth's magnetic pole has flipped over in the past and gone walkabout, as evidenced by magnetic records in rocks which solidified at different times.
Why doesn't an iron body attract pieces of paper?
Iron is not magnetized naturally, so it does not have a magnetic field strong enough to attract pieces of paper. For iron to attract paper, it would need to be magnetized or have a magnetic field induced in it.
How could you use iron filings to tell which of the two bar magnets is stronger?
Iron filings can be used to map the magnetic fields on a magnet by putting pieces of irons on a piece of paper,pass the magnet under the paper,and the side which has more iron filling is the north pole and the side which has less iron filling is the south pole.
Is iron magnetic or non magnetic?
Most types of Iron are magnetic, however depending on its composition and purity, there are kinds that are not magnetic. For example, Steel is mostly Iron, Carbon, and a few other lesser materials, and can be magnetic. Pure Iron is of course magnetic. The iron in your blood, however, is not the magnetic variety. It all depends on the composition.
How do the elements in the iron triad differ from the other transition metals?
iron cobalt and nickel are magnetic the others are not.
Why does an iron nail has more force of attraction than a piece of chalk and rubber band?
Because they have different magnetic properties; iron is strongly ferromagnetic.
Is earth's magnetic field in an closed iron box more than the magnetic field outside the box?
No, the Earth's magnetic field cannot be contained within a closed iron box. Iron is a ferromagnetic material that can distort and redirect magnetic field lines, but it cannot increase the total magnetic field strength. The magnetic field inside the box would be the same as that outside the box.
What effect does annealing have on magnetic iron?
Annealing will soften "magnetic iron" and create a slightly larger metallic crystal structure that should work better for allowing a magnetic field to "flow" through it (which we call permeability). A link is provided.
Is a meteorite always magnetic?
No, not all meteorites are magnetic. Only a subset of meteorites called iron meteorites are typically magnetic due to the presence of iron-nickel alloys. Other types of meteorites, such as stony or stony-iron meteorites, are not magnetic.
What will be the magnetic domains of an iron nail heated up?
You need to strike the hot nail with a hammer to induce the magnetic field. This was a method that blacksmiths used to make weak iron magnets.
What kind of metal is magnetic?
Iron, cobalt, and nickel are the most common metals that exhibit magnetic properties. Other metals, such as steel and some alloys, can also be magnetic depending on their composition and structure.
Why is an iron core inserted in an electro magnet?
Because it develops more magnetic power .
Why are some irons more magnetic than other irons?
It is because some of the metallic objects are more magnetic than each other(more iron than each other).
