Drinks cans are usually made from metal. Some are made from steel. Others are made from aluminium. If we want to recycle the metals in drinks cans, we need to separate cans made from different metals. Suggest a way of separating drinks cans. Explain the physics of your method.
Lucas has had an accident in his workshop. Two boxes of nails have split and become mixed up. Lucas has a bar magnet and thinks he can use it to lift the iron nails out of the mixture. Lucas finds the magnetic field is not strong enough to pick up one nail. Lucas has an electrical toolbox that contains the components shown in the diagram. Explain to Lucas how he could use some components to make his bar magnet stronger.
