The magnetic fields produced by an electromagnet depends on the amount of current and voltage. A single current source can produce multi-field magnetic, the position of the solenoid connected to the current source, where there are multi connectors that can be switched based on the composition of the helical coil and from the data obtained that this can be proved. This research was carried out in a helical and design of copper plates forming solenoid windings, each part of the partition plate numbered 10, 15, 20, 25 and 30 connected to electric currents of 1.5, 3, and 4.5 Ampere and the switch functioned to flow electric current to the partition based on the number of electromagnet plates. The experimental results obtained that the electromagnet design using a copper plate with a switch and partition system The number of plates can produce multi magnetic fields with a single current source with a range of 0 to 8 mT which is measured using Gaussmeter. The benefits of this research will have an impact on physical and engineering research related to the use of electromagnets that are portable and concise but with a single electric current source with multi magnetic fields, besides the next research has the potential to be developed in order to produce high magnetic fields.
