Chapter 9
Magnetic Effects of Current, Electromagnetic Induction, Current Electricity
A compass needle moves when you bring a wire with a current near it. A crane lifts a car with a magnet that you can switch off. A fan turns, and a power station makes electricity, with the same two ideas: a current has a magnetic field, and a magnet and a coil can make a current. In this chapter we study the field of a current, the force that a field makes on a current, the electric motor, the generator, and the safe wiring of a house. Python helps us calculate and draw.
