Lead is not magnetic, but diamagnetic

Pure lead is not magnetic, but has the property of so-called diamagnetism. This special form of reaction of lead to external magnetic sources allows the heavy metal to be used in the construction of electromagnetically based levitation effects. In the traditional sense, lead is neutral.

Magnetism helps find lead lines

Anyone looking for poisonous lead in the water pipes of old buildings usually uses the lead's non-existent magnetism as a search aid. In addition to the other material specifications such as color and texture, a magnetic test is the fastest way to detect pipes made of lead.

Lead is alloyed with the elements antimony, arsenic, sodium and tin, all of which are also non-magnetic. For soldering or welding metals, lead-containing solders are produced, which, depending on the alloy content, can be slightly magnetic.To do this, one of the three ferromagnetic metals iron, nickel or cobalt must be contained in the alloy.

Lead chemically stores electrical voltage

Its non-existent magnetic property allows the electromagnetically neutral use of lead as a storage medium. The typical car batteries consist of lead accumulators, which can store an electrical voltage without a magnetic field through the chemical reaction with sulfuric acid. The isotopic and molecular processes have no physical effect.

The non-magnetic property enables the use of the very dense lead in many protective and shielding devices against radioactive rays of various kinds. The dense atomic mass combines with the specific electrochemical charge of the components to form an effective protective metal.

Electronically neutral metal

Lead conducts electricity and heat, albeit to a technically weak degree, which enables and at the same time limits its usability. The extremely high density gives the non-magnetic lead enormous durability and resistance and makes it electromagnetically neutral. For example, the internal components of a cell phone can contain lead without affecting the radiation behavior during transmission and reception.

Tips & Tricks If you are looking for lead water pipes using a magnet, be aware that the fixings are often made of magnetic metals. If the magnet responds, a retaining clip can be the cause and incorrectly assigned to the pipe or water pipe.
