13 magnetic effects of electric current - class 10
... Electric power to homes is supplied through the mains. It has two wires. One is a live wire (positve wire) with red insulation and the other is a neutral wire (negative wire) with black insulation. The potential difference between the two wires is 220V. The earth wire with green insulation is connec ...

... wire moves up through the field, the current moves in one direction. When the wire moves down through the field, the current moves in the opposite direction. If the wire is held stationary or is moved parallel to the field, no current flows. An electric current is generated in a wire only when the w ...
