Magnet
(OP)
I'm working on a project that requires a hand held magnetic that can be easily turned on and off. Does any one have any suggestions as to where I can find such a magnet.
Another option is to use a permament magnetic, however I will need a guard so that magnetic fields are shielded. The guard must be easy to remove without difficulty.
Thanks

RE: Magnet
Otherwise an electromagnet seems to be able to do what you want, but you should specify more (geometry, force, distance,...) to find a specific product.

RE: Magnet
The only way to turn off a permanent magnet is to use two
Halbach cylinders, one inside the other. The 2 HC produce the same magnetic field B . The out side cylinder turn aroud the inside one to change the magnetic field from 0 T to the maximum field 2B.
