What reading level is Practical Physics for Secondary Schools Fundamental Principles And Applications book?
To quickly assess the difficulty of the text, read a short excerpt:
The north pole of the needle was deflected toward the west 272 PRACTICAL PHYSICS when the current flowed from south to north, as shown in figure 229, while a wire placed under the compass needle caused the north end of the needle to be deflected toward the east.
266. Magnetic field around a current. Inasmuch as the compass needle indi- cates the . Direction of magnetic lines of force, it is evident from Oersted's ex- periment that a current must set up a magnetic field at right angles to the co...nductor. To make this clear, the FIG. 229. Deflection of student may perform the following ex- magnetic needle by periment. Electric current.
We will send a strong current down a vertical wire which passes through a horizontal piece of cardboard. To indicate the magnetic lines of force, we will sprinkle iron filings on the cardboard arid tap it gently while the current is jfy [ ^\ on. The filings ar- ~ ^--^ range themselves in concentric rings about the wire. By placing a small com- pass at various posi- tions on the board, we see that the di- rection of these lines of force is as shown in figure 230.
