Summary
Fish can sense and use magnetic fields for navigation and exhibit altered behavior and development when exposed to natural or artificial magnetic fields. This review covers elasmobranchs and teleosts.
Area of Science:
- Marine Biology
- Biophysics
Context:
- Fish, including elasmobranchs and teleosts, interact with Earth's magnetic field.
- Sensory mechanisms for magnetic field detection include electroreceptors and biogenic magnetite crystals.
Purpose:
- To review current data on how natural and artificial magnetic fields affect fish behavior and development.
- To explore the sensory modalities fish use to perceive magnetic fields.
Summary:
- Magnetic fields influence fish locomotor activity and spatial distribution.
- The geomagnetic field serves as a navigational aid for fish.
- Exposure to magnetic fields can alter fish embryo development, potentially impacting later behavior.
Impact:
- Provides insights into fish sensory biology and navigation.
- Highlights the potential effects of anthropogenic magnetic field changes on fish populations.
- Informs conservation strategies by considering environmental magnetic influences.

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.

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.

The representation of magnetic fields by magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. Each of the magnetic field lines forms a closed loop. The field lines emerge from the north pole (N), loop around to the south pole (S), and continue through the bar magnet back to the north pole.
Magnetic field lines follow several hard-and-fast rules:

A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

Electric fields generated by static charges, often referred to as electrostatic fields, are characteristically different from electric fields created by time-varying magnetic fields. While the former is a conservative field, implying that no net work is done on a test charge if it goes around in a complete loop in the field, the latter is, by definition, not a conservative field; net work is done, and it is proportional to the rate of change of magnetic flux.

3.6K
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...
