 A solenoid is similar to a coil, but instead of having multiple loops of wire one on top of another, the loops are spread out (kind of like a slinky). An example of a solenoid is shown in the figure on the right. As the solenoid is composed of multiple, connected loops, this creates a strong magnetic field in the center of the solenoid, which becomes weaker and wraps around the outside of the solenoid. Because of the superposition of the magnetic field, the field inside the solenoid is actually //constant// both in magnitude and direction. This makes the solenoid a very important application as it is one of the primary ways that we can create a constant magnetic field on Earth.  A solenoid is similar to a coil, but instead of having multiple loops of wire one on top of another, the loops are spread out (kind of like a slinky).
