[[Solenoid]]s consist of a coil of wire enveloping a magnetic core, often composed of [[iron]].<ref name=universetoday/> Solenoids generate an almost uniform field in their centre making them useful in certain scientific experiments. They can also be used to control the movement of a component such as in fuel injectors. [[Superconductor|Superconducting]] magnets are able to generate fields on the order of 10-20 [[Tesla]], 150,000 times stronger than the Earth's magnetic field. They are often used in [[particle accelerator]]s such as the [[Large Hadron Collider]] at [[CERN]] which uses magnets that produce 8.3 Tesla using a current of 11,080 [[Amp]]s.<ref>[https://home.cern/about/engineering/pulling-together-superconducting-electromagnets Pulling together: Superconducting electromagnets] from home.cern</ref> Superconducting magnets are also used in [[Magnetic resonance imaging|MRI machine]]s, and typically produce a field between 0.5-2.0 Tesla.<ref>[https://science.howstuffworks.com/mri1.htm How MRI Works] from science.howstuffworks.com</ref> There are also more theoretical applications such as [[ion]] propulsion systems on spacecraft.<ref name=universetoday/>
