How do you shut of a magnet?

How do you shut of a magnet?

How do you shut of a magnet?

(OP)
Im currently building a machine and I have a peice of copper that is bieng atracted to the magnet, but before it gets to it I need to shut off the magnet somehow.. Is there any possible way of doing this? Can i turn off the magnetic field so the copper isn't attracted?

Thanks in Advance..

RE: How do you shut of a magnet?

Huh?  Copper shouldn't be attracted to a magnet.

RE: How do you shut of a magnet?

patk24: If you are going to so blithely disregard questions/comments that people give you (by saying "whatever"), why should anyone spend time helping you?

RE: How do you shut of a magnet?

Describe the magnet.  Material, permanent, copper wound, configuration?

RE: How do you shut of a magnet?

You can shut off an electromagnet.
A permanent magnet is permanent -- however it is posible
to shunt the magnetic force so it doesn't attract the
previously attracted object zny more ( at least not so strongly)

is there any way to make a electromagnet shut off or stop attracting without using any energy or electriciy, maybe use a trip wire or switch?

RE: How do you shut of a magnet?

If you break the lead to a DC electromagnet you will have an interesting display of electricity.

Perhaps there's more than just copper in the copper wire, if no current is flowing and it is attracted to the magnet?
