The principal exhibits are divided into four pavilions: Earth, Air, Fire, and Water. There is also an outdoor Sci-Tek play area, and Aqua-Tek water play area.
The 1/3 mile long site is often used for staging events, conferences and performances. It won the Enjoy England Gold Award for Business Tourism in 2006.[4]
Every hour, Magna holds a display called "The Big Melt". Its purpose is to demonstrate how steel was made in an electric arc furnace until the steelworks closed in 1993. A furnace is imitated with fog, spark, flame and smoke machines, loudspeakers, lights, and blasts of rapidly burning propane which are ignited at appropriate points in the show. The show can be repeated up to four times an hour, but, in practice, it is usually run once an hour or twice an hour if visitor numbers are very high.
