Solenoids
Wire wound into a tightly packed
helix formation
●
Creates an electromagnetic
field when an electric current is
applied to the coils
●
The direction of the
electromagnetic field is
determined by the Right-Hand
Rule.
●
Applications of Solenoids
Solenoids can convert energy into motion by
moving a ferromagnetic object though it's
core.
●
●
This property can be used for:
-Relays
-Automobile starter solenoids
-Electronic door locks
The Physics of Coil Launchers
Coil launchers are an application of Solenoids
Different Types of Coil Launchers
Single Stage
-Uses one solenoid to launch a projectile
●
Multi Stage
-Uses multiple solenoids
in combination with a
timing circuit to launch
a projectile
