Summary
Magnetotherapy has historical roots, but low-induction fields show limited effectiveness for mental health. Transcranial Magnetic Stimulation (TMS) offers potential but faces challenges in efficacy and practicality.
Area of Science:
- Neuroscience
- Medical Physics
Background:
- Magnetism's therapeutic use dates to antiquity, evolving from natural ores to artificial magnets and electromagnets.
- 19th-century advancements enabled time-varying magnetic fields, prompting studies on their neurological and cognitive impacts.
Observation:
- Magnetotherapy with low-induction fields faces significant doubts regarding efficacy, particularly for mental disorders.
- Transcranial Magnetic Stimulation (TMS) emerged in 1985 for diagnostics and research, with therapeutic applications explored since the 1990s.
Findings:
- TMS effectiveness for mental disorders, especially depression, is not consistently high.
- Fixed-site stimulation may target irrelevant brain areas, causing irritation and limiting therapeutic benefit.
Implications:
- Improving TMS efficacy may require advanced techniques like neuronavigation and functional neuroimaging.
- These enhancements increase cost and reduce the practicality of TMS as a widespread therapeutic tool.

01:30Magnetism
Magnets are commonly found in everyday objects, such as toys, hangers, elevators, doorbells, and computer devices. Experimentation on these magnets shows that all magnets have two poles: one is labeled north (N) and the other south (S). Magnetic poles repel if they are alike and attract if unlike. Moreover, both poles of a magnet attract unmagnetized pieces of iron.

01:27Magnetic Fields
A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.

01:18Other Unique Bacteria
Magnetic bacteria exhibit a directed movement called magnetotaxis, driven by structures called magnetosomes. These magnetosomes consist of chains of magnetic particles made of either magnetite (Fe₃O₄) or greigite (Fe₃S₄) and are organized in a linear conformation by a protein scaffold within invaginations of the cell membrane. The bacteria align along the north–south magnetic field lines, much like a compass needle. They are typically microaerophilic or anaerobic and are commonly found near the...
01:26Diamagnetism
Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets.

01:31Ferromagnetism
Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...
01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
