physics!!!!!!!!! Two identical bar magnets are dropped at the same time from the same height down tubes of the same lengthMagnet A is dropped down an aluminum tube while magnet B is dropped down a plastic (non-conducting) tubeWhich magnet reaches the bottom of the tubes first? Magnet A will not fall through a conducting tubeBoth arrive at the same timeMagnet AMagnet BThe answer depends on the permeability of the plastic in the plastic tub
Can you go and look at it? Hard to say if it will hold up or notIf its something seasonal, it should be fine.
Just check it over for the qualitySome may be fine, but others may not.
You really need to be careful buy fabric or clothes from Walmart.the quality isnt always that goodWalmart is a warehouse store, and is cheaper because the quality isn't as good.
I have used their fabric but just look at it real wellAlso if you have like a Joann's near you their fabrics are fine and can be as inexpensive as Walmart
Magnet A falls more slowly, since an electric current is induced in the aluminum tubeThe electric current creates heat, and this energy must be supplied by the falling magnetThe effect is that of a friction brake.
