This brings up an excellent point

Robert : That makes sense for explaining why a current of electrons flowing through a wire causes this compass needle to move, or how currents in the Earth’s outer core generate the geomagnetic field. But a bar   Magnet for sale  or the compass needle itself are just pieces of metal without an electrical current running through them.

Steve : Or are they? At the microscopic level, there are loads of electrons whizzing around the atoms &  molecules that make up all solid.

Robert : Right. This brings up an excellent point. The magnetic behavior of all everyday object is influenced by a fascinating combination of effects ranging from the level of particles, to atoms, collections of atoms, &  collections of collections of atoms. First, individual particles.

Magnetic Balls There are a few big players to look out for when buying your magnets for magnet fishing.Here are some of the magnet manufacturers names you should look for:
Sphere Magnet Before you go out to your local hardware store or shop online and buy a magnet you need to know just a little bit more information to ensure you get the best magnet.

Magnetic Balls Neodymium magnets (actually an alloy, Nd2Fe14B) are the strongest permanent magnets known. A neodymium magnet of a few grams can lift a thousand times its own weight. These magnets are cheaper, lighter, and stronger than samarium–cobalt magnets.

rare earth magnet Neodymium ions in various types of ionic crystals, and also in glasses, act as a laser gain medium, typically emitting 1064 nm light from a particular atomic transition in the neodymium ion, after being “pumped” into excitation from an external source

Unlike the everyday workings of gravity &  electricity, permanent magnets can only be fully understood as a quantum mechanical effect. In much the same way that particles like electrons &  quarks have fundamental properties called mass &  electrical charge, most particles also have another intrinsic property called tiny magnet. Just kidding, it’s called intrinsic magnetic moment. But really, that’s just technical mumbo jumbo saying that particles with electric charge also happen to be tiny magnets.
