To quickly assess the difficulty of the text, read a short excerpt:
— Bring a piece of soft iron into con- tact with the pole of a bar magnet, and dip the end of the 222 MAGNETISM AND ELEOTBICITY. soft iron in iron filings. What is the result? Remove the soft iron from the magnet, and note what takes place. Place upon a box or block of wood the bar magnet, and upon another box the piece of soft iron. Move the soft ;7 / y iron near the bar magnet, but not near Fio. JOS. ^ enough to touch (Fig. 196). Hold a piece of paper with iron filings on it so that the filin...gs may touch both ends of the soft iron. Are they retained by the iron ? Determine the kind of magnetism in the poles of the soft iron, by using a magnetized knitting needle suspended in a paper stirrup. When this is determined, remove the bar magnet. What is the effect of removing the magnet ? The magnetism which exists tem,porarUy in soft iron when in contact with a fnagnet, or when brought within the magnetic field, is coiled Induced Magnetism. Devise an experiment by which you can ascertain whether magnetism may be induced by induced magnetism.
