Secure transport for N42 magnets
Secure transport for N42 magnets
(OP)
Is there a way to dampen or suppress the magnetic field of a N42 Neodymium magnet for safe travel without the heighten threat of flying objects or wiping computers. I know that there is no way to completely suppress the field, but slightly suppress around 10%-25% less powerful?

However this may be not sufficient for aviation regulations.
A better protection with not too much weight added is achieved by putting two layers of carbon steel sheet separated by a thickness of one to two centimeters of a packing material.
Of course the magnets must be firmly held in place by a suitable filling inside the box.

If you are transporting by air you will need to set them up in a very magnetically clean room with a sensitive gauss meter and experiment with shunting the field.

If you try this, it's very important for the stacks to have the same number of magnets. If one stack is longer by one magnet, lots of extra flux will travel out of the box.
If the quantity of magnets is large and two stacks is unwieldy, make 4, 6, 8, etc. stacks and stick them together (magnetically). It's important for each stack to have a neighbor.
Also, prex mentioned this but it is worth repeating: There are strict aviation regulations regarding shipping magnets by air. Each box must be tested for stray flux.

So a slab about 0.1" thick on each end will pretty much zero out the end fields with alternating poles. Then some thin sheets of the same material on the sides should eliminate the remaining fields.
