I wound 1 km of copper wire, 1 mm thick and weighing 7 kg, around the Faraday gyroscope (which consists of around 75 copper chambers mounted on the circumference of a rotating glass disk). I then set the disk in rotation to observe whether the earth's permanent magnetic field interacts with the Faraday cages and generates measurable induction currents in the copper coil. Ps: Please note the measuring device at minute 2:38!
