What happens when metal filings are dropped on a sheet of paper that has a bar magnet beneath the paper?
A bar magnet creates an invisible magnetic field around it, and magnetic metals such as iron are attracted to the magnet. Any metal structure is then included in the magnetic field lines. For iron filings on the sheet of paper, they will group into clusters near the poles, and also form an oval pattern along the length of the magnet, representing the magnetic field lines. The field is bulged outward nearest the center of the magnet's length. This displays the approximate two-dimensional shape of the three-dimensional magnetic field. For a picture, see the related link.
How can you determine the poles of an odd shaped magnet?
You place the magnet under a piece of paper, and then sprinkle some iron filings on the paper. The iron filings will line up along the magnetic lines of force, which will show very clearly where the magnetic poles are.
How does rubbing a magnet along an iron nail create a temporary magnet?
No. It only needs to pass through a magnetic field to become magnetized. It does not need to come into physical contact with the magnet producing that field. This is because the process of magnetization has to do with electromagnetic induction rather than physical contact. You can perform a simple experiment at home to prove this point. You'll need a bar magnet, a paper clip, and a thin sheet of paper. Place the paper between the magnet and the clip. Rub the clip against the paper on top of the magnet, and observe that the clip will still become magnetized even though it is not in physical contact with the magnet.
Why a freely suspended magnet always rest in north and south direction?
A magnet aligns itself along the earth's magnetic field, with its north pole pointing to a location called 'Magnetic North', so called to distinguish it from 'True North'. The magnetic polarity of the location we call 'Magnetic North' is south.
How does a solenoid act as a magnet?
When current is passed through a solenoid coil, magnetic field produced due to each turn of solenoid coil is in the same direction. As a result the resultant magnetic field is very strong and uniform. The field lines inside the solenoid are in the form of parallel straight lines along the axis of solenoid. Thus, the solenoid behaves like a bar magnet.
How can iron filings provide evidence that a bar magnet has a magnetic field?
They tend to align along the magnetic field lines.

When a magnet is suspended or freely aligned in which direction will it alight?
Along an axis between the North and South Magnetic Poles.

Why magnetism at the centre of a bar magnet is zero?
F = mB - mB =0 a bar magnet is placed in a uniform magnetic field B, its poles +m and -m experience force mB and mB along and opposite to the direction of magnetic field B.

What happens when you place iron fillings around a magnet?
The fillings align themselves according to the magnetic field created by the magnet. *See the related links to images of the fillings behaving this way, along with a drawing representing the magnetic fields to which the filings align. You can see how the fillings behave similarly in each of the different photos. (see also related question below)
How to find the North Pole of a ring magnet?
we can find the poles of a ring magnet by tieing thread along the circumference of it and suspend it with a torsionless string then it will allign itself according to earth magnetic field
What is the list for the characteristics of a magnetic field produced by a current?
A magnetic field is a change in energy within a volume of space. A magnetograph can be created by placing a piece of paper over a magnet and sprinkling the paper with iron filings. The particles align themselves with the lines of magnetic force produced by the magnet. The magnetic lines of force show where the magnetic field exits the material at one pole and reenters the material at another pole along the length of the magnet. It should be noted that the magnetic lines of force exist in three dimensions but are only seen in two dimensions in the image.
What is the difference between the magnetic fields of horseshoe and bar magnets?
Horseshoe magnets have a stronger magnetic field at their poles compared to bar magnets, which have a more uniform magnetic field along their length. The horseshoe shape concentrates the magnetic field lines at the poles, making them more effective for picking up magnetic materials. Bar magnets have a weaker magnetic field at their ends but are more versatile in their application.
Why does iron sand form a pattern when sprinkled over a magnet?
If this happens, it means that the iron contained in the sand will orient itself along the magnetic field lines.
