Treasure hunting and fishing with magnets

If you thought magnets were only for the fridge, you're in for a surprise. Because with the right magnet you can fish a bicycle out of the lake or go treasure hunting (geocaching) and find magnetic metals. 

Fish with magnets

When choosing a magnet for fishing, you need to decide on some things: 

1. How heavy things? Eg. a magnetic fishpond or a larger object like a bicycle.
2. Should the magnet be able to withstand impact?
3. Should the magnet be able to withstand water without rusting?
4. Is it a direct drag, or does current/wind come and challenge the carrying capacity?
5. Should the fishing rod be operated by children or adults?

(1) If you have to fish sole thing, you need a very strong magnet. And if you are fishing in a lake, the magnet must be able to withstand impacts. Read more here about magnetfishing. If, on the other hand, you just want to make a magnetic fish pond as a party game, you don't need such strong magnets, and here a small ring magnet be preferable, as it is strong enough to fish up small paper fish with, and it is not that dangerous for children . 

(2) and (3) These are essentially the same as above with fishing in a lake. And if you can answer yes to one of these things, you should go for a rubber magnet or a pot magnet, both of which can withstand impacts. If not, you have virtually free choice on all shelves with our power magnets.

(4) A direct pull is the least stressful for a magnet. Because as soon as it becomes crooked, the magnetism is challenged approx. x4. That is if you want to be able to pull the magnet sideways, you must multiply your strength requirement by at least a factor of 4. We are happy to do this calculation for you. 

(5) Magnets are not toys - they are fun and exciting, but they should never be used by children without adult supervision. And always carefully consider whether the strength requirement can be lowered when dealing with children, as two magnets at full speed against each other can destroy a hand!

Magnetic treasure hunt

Geocaching is a treasure hunt with GPS - it involves finding small hidden treasures on a route. They don't have much value, so it's mostly about the excitement and finding more than your friends... there's a lot of excitement because the little box can be hidden under the bench, up in the tree or stuck behind a metal plate .

Magnets are used to attach the small boxes to a magnetic material. In the big cities in Denmark, there are many fun options: benches, containers, lampposts, etc. And you can also use magnets to close the boxes in a fun way, so that whoever finds the treasure has to figure out how to open the box. It gives an extra dimension to geocaching, that you make something extra out of your entries. Precisely because the little treasure has little value apart from the voltage.

Strength requirements therefore depend on what the magnets are to be used for. We could easily come up with a lot of examples, but it is easier for us if you contact our customer service to find out what you need for your magnetic treasure hunt.
