What reading level is General Science book?
To quickly assess the difficulty of the text, read a short excerpt:
The reverse of this is also MAGNETISM AND ELECTRICITY 209 true. When the magnet is placed in or removed from a coil of wire, a current is produced in the wire.
Experiment 58. Connect a coil of several hundred turns of insulated wire with a galvanometer (Figure 184). Now bring the pole of a bar or horseshoe magnet suddenly into the coil and notice the deflection of the pointer of the galvanom- eter. When the pointer comes to rest, remove the magnet quickly ; the pointer will again be de- flected..., but in the op- posite direction.
Experiments will show that it makes FIG. 184. When the permanent magnet is placed in the coil a current of electricity is in- duced in the coil as is shown by the deflection of the galvanometer needle.
no difference whether the coil be held sta- tionary and the magnet placed in it, or the magnet held stationary and the coil moved over it. The current in the coil of wire is made when it moves through a mag- netic field. This is the principle of the dynamo (Figure 185).
