A solenoid is simply a tightly-wound coil of wire, with its length being substantially greater than its diameter. When an electric current runs through the solenoid, it exerts a uniform magnetic field from the center of the coil. Solenoids have a wide range of applications in the modern world, as the magnetic field which is created by the electric current can be turned on or off, and can be strengthened or weakened by adjusting the electric current. From car doors to medical equipment, solenoids are a common part of our everyday lives.
The Main Idea
Solenoids can be found in electric locking mechanisms, medical equipment, cars, air conditioning systems, and numerous other devices. But first it is imperative that one understands how a solenoid produces a magnetic field in order to comprehend their usage in everyday life.
A Mathematical Model
The formula for the magnetic field of a solenoid is as follows:
- [math]\displaystyle{ B = \mu_0 \frac{N I}{l}. }[/math] where N is the number of turns in the coil, [math]\displaystyle{ \mu_0 }[/math] is the magnetic constant, I is the electric current, and [math]\displaystyle{ l }[/math] is the length of the solenoid.
