What is empirical  evidence?
Empirical evidence is information acquired by observation or experimentation. This data is recorded and analyzed by scientists and is a central process as part of the scientific method. Why is everything posted on climate by Inhere always horseshit?
Poor old  Inhere on finders still does not know the difference between weather and climate!The silly old goat seems to think because some places have recently had very cold weather that this brings into question  AGW!  Only right wing rabble rubbish climate deniers like horseshit Inhere don't  seem to understand  that AGW will mean that some regions of the earth will become colder!
Why is  onehalfgram :1/2 wit always wrong  on the QED?

Hi All,

Ebay has 12v electro magnets of varying lifting capacities up to 100kg, im looking at the 50kg ones to make a rake to remove rusty metal for detecting,you can buy 3 for $67

Problem is I don't know really which ones to try , are they strong enough to do the job, I was thinkin of putting 3 in a row and fix some wheels on and connect up to my 4.4 kva genny which has a 12v battery charger supply line

If that doesn't work I could use my transformer power supply that's converts 240v back to 12v at 30amps

If these work I imagine there will be a rush on them so can anyone help me out

I know of a fellow who made a "rake" useing simple rare earth magnets
basically its just a plastic tube with a row of magnets in it, works fine
picks up most of the surface junk.

Hi 6666,

Yeah, seen them before not very powerful but I think these sound like they would have some serious grunt but don't know enough about them to jump in and purchase just yet

Cheers Ron
