Their lengths aren't exactly the same but are close to 50cm.  
 + 
 +A smaller-diameter copper tube with a slit is also available, as well as a pair of aluminum tubes ((which work, but produce a smaller braking force because the conductivity of aluminum is lower)) and a long solenoid. ((which at first glance seems like it should work, but doesn'​t due to the way the induced currents cancel. If you can measure precisely enough, it may be possible to register a (very small) difference.))
