Fun With Magnetism.
BOOK AND COMPLETE OUTFIT FOR SIXTY-ONE EXPERIMENTS IN MAGNETISM...
[Illustration]
Children like to do experiments; and in this way, better than in any
other, _a practical knowledge of the elements of magnetism_ may be
obtained.
These experiments, although arranged to _amuse_ boys and girls, have
been found to be very _useful in the class-room_ to supplement the
ordinary exercises given in text-books of science.
To secure the _best possible quality of apparatus_, the horseshoe
magnets were made at Sheffield, England, especially for these sets.
They are new and strong. Other parts of the apparatus have also been
selected and made with great care, to adapt them particularly to these
experiments.--_From the author's preface._
=CONTENTS.=--Experiments With Horseshoe Magnet.--Experiments
With Magnetized Needles.--Experiments With Needles,
Corks, Wires, Nails, etc.--Experiments With Bar
Magnets.--Experiments With Floating Magnets.--Miscellaneous
Experiments.--Miscellaneous Illustrations showing what very
small children can do with the Apparatus.--Diagrams showing
how Magnetized Needles may be used by little children to
make hundreds of pretty designs upon paper.
