On lifting off the paper, most of the filings will adhere to it, and can be brushed off when dry, leaving dark marks on the paper. Place a small magnetic needle successively in different parts of the magnetic field, as marked out by the filings before removing the magnet, and notice its position with reference to the line of force passing through the support. A suitable needle may be constructed as follows: Straighten a piece of watch-spring, cut from it a lozenge-shaped piece 15 mm. long, and drill a hole 1 mm. in diameter through the centre. Cement, with a little wax, a small cap exactly over this hole to serve as a bearing. To make such a cap, heat the end of a very small glass tube in a Bunsen flame till the glass, by contracting, closes the end. Cut off, with a file, a piece about 3 mm. long, and you will have a cap with a smooth conical hole in it for the reception of the supporting pivot. For a pivot, break off the point of a sewing-needle, and insert it in a piece of wood 1 cm. square and 2 mm. thick for a base. If the needle is not level after magnetization, adjust it with a little wax. 301. Exercise.--Represent, by a curve, the change in the magnetic strength as you go from the poles of a magnet to the centre. Magnetize, as uniformly as possible, a heavy knitting-needle. This is best done by the method known as Divided Touch. It consists in fixing the needle lengthwise between the opposite poles of two permanent magnets, and, while under their induction, stroke the needle, each half, with the pole of another magnet of the same name as the corresponding inducing pole, the stroking-magnets being held in the hands at an angle of about 30 degr...
