What is a magnetic geocache?
A DIY geocaching container made from an old log cut in half and eight D84PC-BLK magnets. Geocaching is a game/sport/activity where participants use a GPS to find hidden caches. It’s like a technology-assisted treasure hunt. Caches are usually placed in nice locations for a walk or hike.
What is a magnetic nano geocache?
Use as geocache containers They are widely known in the geocaching community as one of the smallest geocache containers. Magnetic nano geocaches only contain a thin, rolled-up paper sheet for geocachers to sign their username initials on.
What are the magnetic properties of nanomaterials?
Magnetic Property The properties of magnetic nanoparticles depend on the synthesis method and chemical structure. In most cases, the magnetic nanoparticles range from 1 to 100 nm in size and can display superparamagnetism.
What should you not put in a geocache?
Explosives, fireworks, ammunition, lighters, knives (including pocket knives and multi-tools), drugs, alcohol and any illicit material should not be placed in a cache. If someone other than you places an inappropriate item in a cache that you own and this is reported, the cache may be temporarily disabled.
Can I make my own geocache?
We recommend finding at least 20 geocaches before you hide your own. Try to find different cache types, different sizes, and caches hidden by different people. This way you can have an idea of what is already out there, what other geocachers will expect from your cache, and what kind of caches you find inspiring.
Where are magnetic nanoparticles used?
Magnetic nanoparticles (MNPs) have shown promise in a number of biomedical applications, including: magnetic hyperthermia, enhancing magnetic resonance imaging (MRI) data, supplementing tissue engineering efforts and improving the delivery of drugs to difficult to reach microniches.
Which are magnetic nanoparticles?
Magnetic nanoparticles are a class of nanoparticle that can be manipulated using magnetic fields. Such particles commonly consist of two components, a magnetic material, often iron, nickel and cobalt, and a chemical component that has functionality.
Can you take stuff from geocaches?
While some caches host trackables or unique SWAG items, some geocaches aren’t so lucky. The etiquette around geocaching SWAG is simple. If you take something, leave something behind of equal or greater value.
Can you take from geocaches?
Geocaching Etiquette for Cache Finders Take one item out (if you want to), but only if you replace it with a new item of equal or higher value. If the item you take is a “trackable” (see below), then you also have an obligation to move that item to a new cache.
Does geocaching cost money?
There are plenty of public geocaches out there. You can find them without paying a penny (other than your gas and the expense of a GPS). Therefore you are geocaching for FREE. You don’t have to pay anything…and you can still geocache.
Is a fridge magnet stronger than the Earth’s magnetic field?
In the immediate surrounding of the fridge magnet, the fridge magnet magnetic field is stronger than the one of the Earth, but at any larger distance, the Earth magnetic field is stronger. The larger Earth magnetic field is not significantly affected.
Are Zen Magnets illegal?
In 2014, the CPSC finalized their rule which banned magnet sets such as Zen Magnets/Neoballs for any age group. Zen Magnets immediately appealed this decision in federal court.
Why are neodymium magnets banned?
An online trend that involves using tiny magnets as fake tongue piercings has led the NHS to call for them to be banned amid people swallowing them. Ingesting more than one of them can be life-threatening and cause significant damage within hours.
Who invented magnetic nanoparticles?
Frenkel and Dorfman [45] were the first to predict that a particle of ferromagnetic material, below a critical particle size (<15 nm for the common materials), would consist of a single magnetic domain, i.e., a particle that is in a state of uniform magnetization at any field.
