may be reversed, — the conductor remaining stationary and the field moving, — and the result will be the same. Figure 209 shows a per-manent magnet (M) thrust into a coil of wire (C), the endsof the coil being connected through the galvanometer (G).When this is done, the galvanometer will deflect,… … Figure 209. — A Permanent MagnetBeing Thrust into a Coil of Wire. AN ELECTRO-MAGNET IN A COIL OF WIRE 201 If the magnet were pulled out, the lines of force wouldbe cut in the opposite direction, and the galvanometer woulddeflect in the opposite direction, showing that the current isreversed.
