List of parts.

Casing - Any casing will do in this is case a cake tin of 7 inchs wide and 4 inches tall was used.

Small battery powered motor - I purchased three on ebay for £3 plus postage.

Magnetic's - The magnetic's used on the base of the Em Pump are rare earth magnetics from a few old hardrives but you can use other ones if desired. The magnetics on the rotor were small ones ordered on Ebay for few pounds again I suspect a similar result could be achieved with some fridge magnets.

Rotor - Simple lollipop stick . I think other items could used in its place.

PP3 Battery connector - Readily available and purchased cheaply on Ebay for a pound or two.

Aroldite - I found this be the best glue to use , best to leave for 24hrs at each stage so it can reach its full strength.

I initally wanted to purchase an EM Pump and eventually came across a diagram of how to construct one very cheaply from items around the house. This could save on having to buy any unnecessary equipment.

When a 9v battery is connected the PP3 battery the rotor starts to spin very fast ( It is recommeded anything electrical such as mobiles / Laptops are kept well away as it could cause them damage ) the EM Pump creates a massive amount of EM energy for a ghost / spirit to feed on theoretically. This will also act as beacon for any entities in the area.
