Apparatus for demonstrating electromagnetic induction

Apparatus for demonstrating Faraday's discovery of electromagnetic induction. Two wooden panels attached together so one is upright, near the top of this there is a black box attached with a white line in the centre. This box looks to be wodden and painted as some of the paint is coming off one end. On the base there are two attachments both with a wire coming out. This wire continues up the vertical panel and is coiled up. This is held in place by a black mount.
