How can you tell the difference between an aluminium anode rod vs a magnesium anode rod?

I have an old "new" anode rod that I no longer recall if it is aluminium or magnesium. Is there an easy way to tell?

I prefer magnesium as it should give better protection and also is better for your health.

Thanks
 
I think both of those are the standards rods I used a zinc alloy
because the hot water after sitting over ire would produce
a sulfur smell and by changing it to zinc alloy it stopped
the smell I think if you goggled for pics you may see the diffrence
good luck
