Why are the iron filings clustered at the ends of the magnet?

Give Reason If you dip a magnet into a bowl with iron filings, most of the filings get attracted to the ends of the magnet .

When a magnet is dipped in a bowl of iron filings, the poles of the magnet attract

Storage roots found in clusters at base of stem are

Why is soft iron used as the core of the electromagnet in an electric bell ?

An iron needles is attracted to the ends of a bar magnet but not to the middle region of the magnet. Is the material making up the ends of a bar magnet different from that of the middle region?

A small iron bar is kept near the north pole of a bar magnet. How does the iron bar acquire magnetism ? Draw a diagram to show the polarity on the iron bar. What will happen if the magnet is removed ?

Pieces of soft iron used for the storage of magnets

A circular loop of radius a, carrying a current I, is placed in a tow dimensional magnetic field. The centre of the loop coincides with the centre of the filed The strenght of the magnetic field at the pariphery of the loop is B. find the magnetic force on the wire.

STATEMENT-1 : When a soft iron bar is suspended freely in earth's magnet field it does not show directional property . and STATEMENT-2 : When soft iron is placed in magnetic field it does not experience force .

The diagram below shows a current carrying loop or a circular coil passing through a sheet of cardboard at the points M and N. The sheet of cardboard is sprinkled uniformly with iron filings. Draw the pattern of arrangement of the iron filings when current is passed through the loop.
