ELECTRO-MAGNETIC MACHINES.
The experiments already described in illustration of some of the phenomena of electro-magnetism are of such a simple nature that they may be comprehended without difficulty; but it is not such an easy task to appreciate the curious fact of an invisible power producing motion.
It has already been explained that a copper or other metallic wire conveying a current of electricity becomes for the time endowed with a magnetic power, and if held above, or below, or close to, a suspended magnetized steel needle, affects it in a very marked degree, causing it to move to the right or left, according to the _direction_ of the electric current; and in order to form some notion of the condition of a metallic wire whilst the electricity is passing through it, the annexed diagrams may be referred to.

Chapter 17 of The Boy's Playbook of Science by John Henry Pepper holds 75 sentences, grouped into 15 reading sections of at most 5 sentences. The text is the source edition, unabridged, and the chapter records which sentences cover which part of the work so that nothing is dropped. Every word can be tapped for its pronunciation and dictionary entry.

What does chapter 17 of The Boy's Playbook of Science contain?

Chapter 17 holds 75 sentences of The Boy's Playbook of Science, unabridged, divided into 15 reading sections.

This page carries chapter 17 of The Boy's Playbook of Science by John Henry Pepper exactly as it stands in the source edition, without abridgement. It runs to 75 sentences, grouped into 15 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.

How do I study chapter 17 of The Boy's Playbook of Science?

Work through the 15 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 15 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.

Can chapter 17 be read aloud to me?

Yes — every sentence and every individual word in chapter 17 can be played aloud in United States English.

Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
