WOW Thanks ,,, great pics ,, hvat type of magnet are the best ?

Using a larger Neodymium magnet on a pole to collect meteorites.  This meteorite is mostly iron. This shape of magnet isn't ideal for attaching to a pick although it is very strong and there are ways to tape it (with duct tape) to a pole or a pick if you are determined.
.
I usually carry a small prospecting pick or a geologists pick on my belt when I am detecting and use it to turn over locks and rocks etc.  I often have a strong neodymium magnet taped either to the head of the pick (so it doesn't slide when the pick strikes against anything) or I will get a magnet with a hole through it and I will place a screw through the magnet and into the wooden handle of my pick.  Just remember to keep it away from your wallet if you have credit cards inside it. 
.
I know that the 'Mythbusters' show on television claimed that  magnets can't erase a credit card but they were wrong as I have witnessed this happen in front of me twice. It should be safer if you keep your cards from coming in direct contact with a strong magnet.

A stony meteorite containing just enough iron to attract small magnets.

A slice of a stony meteorite that contains iron (the sulvery specks).  The iron in this instance wasn't enough to attract a magnet but it was enough to find with a metal detector.

.
A magnet on the end of a short-handled pick can help you pick out bits of iron off the ground to speed up your detecting process and eliminate iron-based trash or even help you find meteorites.  Those magnets are cheap and you only need one.  Just remember that larger magnets of an inch and a half or larger can be VERY dangerous if you have two of them and they suddenly snap together.  You can break your fingers that way.  Just one magnet is enough and it's usually much safer than two.  I'd recommend one that is about an inch or an inch and a half wide to do the job.
.
Most meteorites contain iron.  Iron meteorites contain a lot of iron so they're easily found with a magnet... but even stony-iron meteorites contain enough iron to respond to your metal detector.
.
If you buy a metal detector to look for meteorites with, be sure to turn OFF the "discrimination" so that the detector will not reject iron.  This way, if you find a meteorites, the detector will not assume that the iron is 'trash' and then ignore it.
