Help required: creating an RFID locking mechanism Answered

I am looking to create a device which is

An electromagnet with two parts. When connected they create a magnetic field. The magnets can be separated without an alarm sounding, if the magnetic field is stopped using an RFID device. If the magnets are separated without the RFID device I would like an alarm to sound.

Can any of you help me design this device, if so I would like to discuss the opportunity to get you on board my business with me.
