Sensitivity of the homing pigeon to an Earth-strength magnetic field

Nature, 1977
Although the Earth’s magnetic field appears to be involved in orientation, previous laboratory experiments have been unable to confirm the magnetic sensitivity of homing pigeons. In the experiments described here, a flight tunnel was constructed within a shielded chamber and used to train three pairs of pigeons (Columba livia) to discriminate between ...

The Strength and Structure of the Coronal Magnetic Field

Space Science Reviews, 2005
I discuss a method for determining the strength and spatial structure of the coronal magnetic field by observations of the Faraday rotation of a radio galaxy which is in conjunction with the Sun. Given a knowledge of the plasma density in the outer corona, and the magnetic field sector structure (both independently available), the strength of the ...

Control over Janus micromotors by the strength of a magnetic field

Nanoscale, 2013
For transportation of molecules or biological cells using artificial motors, the control over their motion, i.e. direction and speed of transfer, is important. Here, we demonstrate that modification of the velocity and orientation of a magnetic Janus particle can be efficiently controlled by tuning the strength of an applied homogeneous magnetic field.

Magnetic Resonance for Arbitrary Field Strengths

Physical Review, 1955
Starting from a microscopic viewpoint, the steady-state value of the magnetization of a system of moments has been calculated semiclassically and quantum mechanically when the external field has a circularly polarized component perpendicular to the constant component.

Study of the Magnetic Field Strength in the Eight-Figure Coils

2018
Along with the progress of the technology, people have an increasing demand of electricity. In the process of power transmission, the copper loss and wire aging will bring hidden trouble to the equipment. On special occasions, such as mining engineering and underwater working, the traditional power transmission system with wire will lead fatal harm to ...

Magnetic field strength issues in magnetic resonance imaging.

Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes, 1994
The authors review the current status of magnetic resonance imaging (MRI) with respect to magnetic field strength. The discussion covers the practical aspects of MRI--safety, throughput and costs--as well as the clinical aspects as they are influenced by field strength.
