Yeah. Apparently they do look exactly alike:

What are their purposes?
The brushes glide along the commutator and transmit the electric current to the rotating armature (Anker) in the motor.
This is the first time I've bothered learning about this. Thanks!
Never to late to learn!
Quality reply! Appreciate you taking the time. :)
Aha, thanks. I wonder how it ended up in a park.
Fell out, either from a destroyed tool or simply fell out, as they're held in with a simple screw cap.
Could've also fallen/dropped by someone who repairs such things, as it's sometimea an easily replaceable part.
To make an electrical connection to a moving (rotating) part.
