Summary
Plants respond to the Earth's geomagnetic field (GMF), but its effects on growth are unclear. This review explores how magnetic fields influence plant development and evolution.
Area of Science:
- Plant biology
- Geomagnetism
- Environmental science
Background:
- Plants perceive various environmental stimuli, including light, gravity, touch, and electrical signals.
- The Earth's geomagnetic field (GMF) is a ubiquitous environmental factor that influences organisms.
- While plant responses to phototropism, gravitropism, and thigmotropism are well-documented, the impact of GMF on plant physiology remains largely unexplored.
Purpose of the Study:
- To review the current understanding of how altered magnetic field (MF) conditions affect plant growth and development.
- To discuss the potential role of the GMF in plant evolution.
- To explore the nature of the magnetoreceptor in plants.
Main Methods:
- Literature review of studies investigating plant responses to magnetic fields.
- Analysis of plant reactions to MF values both lower and higher than the GMF.
- Discussion of theoretical models and experimental evidence regarding magnetoreception in plants.
Main Results:
- Altering magnetic field conditions can significantly impact various aspects of plant growth and development.
- Plants exhibit differential responses to magnetic field strengths compared to the natural GMF.
- Evidence suggests a role for GMF in plant evolution, though the precise mechanisms are debated.
Conclusions:
- The influence of the geomagnetic field on plants warrants further investigation.
- Understanding plant responses to magnetic fields could reveal novel mechanisms of environmental sensing.
- Further research into plant magnetoreception may elucidate evolutionary adaptations and potential applications in agriculture.

5.9K
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.

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...

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.
An individual magnetic pole cannot be isolated. No matter how small, every piece of a magnet contains a north pole and a south...
