wow, if I found that I'd call the bomb squad.

[Detn8er]

I just talked with Mike on the phone......... I'm not an expert but I do pretend to be one at work. 
This is not a device that will go Kaboom...... Mike is going to try my suggestion and he'll let us know later. I bet him a hundred dollars to a burnt biscuit and I hope I'm right because I don't have a hundred dollars or a burnt biscuit.

Wait, it was only $75...

Anyhow... Mark supposed it was a magnet and that the wire is for pulling it around to
pick up stuff.

It's a magnet

 Fuse.

[MacDragon]

FUSE OR AN OLD BATTERY.

[olddog1946]

A very large fuse or a pipe bomb.

[Bonzo]

Overhead power fuse? Look to see if there is a "pop up" indicator on one side like on a chicken or turkey.
Looking at it closer in perspective with the leaves and that it's tabs at the ends seem to be a different size so it can only be put in one way, it may be a resistor of some sort. Maybe?

So you owe me a burnt biscuit.  Never doubt the knowledge of The Detn8er.....He is one of those geenusises. Now you have a new toy to pull around the yard and find old artifacts.....Old time metal detector.
