nxperiments with the Magnat.

Magnetic attraction is both curious and interesting.
And many amusing experiments may be performed
with it, thus making the magnet doubly attractive
to young people.
The magnetic attraction will not be destroyed by
interposing obstacles between the magnet and the
iron.
Lay small needle on piece of glass; and put the
magnet under the glass il viii still attract the
needle. The same effects viii take place il board
be interposed between the magnet and the iron This
property Of the magnet has afforded the means of
some very amusing receptions.
A little figure of a man has been made to spell
persons name. The hand, in which was piece Of
iron, rested on board, under which person, con
cealed from view, with powerful magnet, eontrlved
to carry it from letter to letter. until the word was
made up.
The figure of a goose or swan with piece of iron
concealed about the head, is set to float in water.
rod with concealed magnet at the end, is present
ed to the bird and it swms after it. The effect is
still amusing when some food is put on the end
of the rod.
The figure of fish is thrown into the water, with
small magnet concealed in its mouth. OF course if
baited hook be suspended near it, the magnet and
iron, by mutual attraction, will bring the fish to the
bait.
Put piece of iron in one scale of balance, and
an equal weight in the other scale bring magnet
under the scale which contains the iron and it will
draw it down. Reverse this experiment, and put the
magnet in the scale. and balance it bring the iron
under it, and it will draw down the magnet Sus-
pend magnet by a string and bring piece Of iron
near it, and it will attract.
If a magnet suspended by one string, and piece
of iron suspended by another, be brought near one
another, they viii mutually attract each other and
be drawn TO point between.
Suspend a magnet nicely poised by thread, and
it will point north and SOUTH the end pointing
invariably the same way.
Rub fine needle with a magnet, and lay it gently
on the surface Of the water and il will point north
and south. Rub various needles with the magnst,
run them through small pieces Of cork, and put them
to swim in water they will all point north and SOUTH
and the end will Invariably point the way.
This mode of finding the north is sometimes Of the
utmost service at sea, when the compass destroyed
Opposite poles attract; poles Of the same name
repel. Take two magnets or two needles rubbed
with the magnet and bring the north and south poles
together, and they attract.
Bring the north poles each other, and they
pei. Rub needle with magnet, and run it through
piece of cork, and put it to float in water Hold
the north pole Of magnet near its north pole, and it
VIII keep lying away to avoid it. 1t may be chased
from side to side OF basin. On the other hand an
opposite pole will Immediately attract.
Rub four or five needles, and you may lift them up
as 10 string, the north pole of one needle adhering
TO the south pole of another.
Put magnet under piece Of glass, and sprinkle
iron filings on it they will arrange themselves in
manner that will be very surprising At each pole
will be vast abundance, standing erect, and there
will be fewer and fewer they recede until there are
scarcely any in the middle. Ii the iron.dings are
sprinkled on the magnet ITSELF they will arrange
themselves in a manner very striking.
Lay needle exactly between the north and south
poles it will move towards neither.
