The invention relates to a process for determining the direction of the earth's magnetic field, which may be subject to interference from magnetic materials in the device and electric currents in the device, by means of an electronic magnetic compass containing three magnetic field sensors and two...
magnetic force(iv)The shape of the Earth's magnetic field is as though there were a bar magnet at the centre of the Earth, aligned approximately on the North-South axis.If the plane flies west to east, but above the equator, the wing tips do not become charged.Explain why.(Magnetic) ...
The discovery that Earth's inner core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth's magnetic field. 选项: ...
The model tests performed and the 3D field applications to real magnetic data confirm the useful properties of the transforms suggested here.Petar StavrevDepartment of Applied Geophysics, University of Mining & Geology ‘St. Ivan Rilski’, Studentski grad, 1700 Sofia, Bulgaria.,; E‐mail: stavrev...
What are the two factors that determine the strength of the magnetic field of a bar magnet? What is a magnetic field, how is it defined and what does it tell you? What causes the magnetic field of the earth? What cause the magnetism? What is the difference between magnetic fi...
Magnetic Field Due To Current Carrying Circular Loop View Solution The direction of magnetic field due to a current carrying conductor can be determined by Ampere's ___rule. View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, ...
The precise value of what angle from North one should turn to face the Qibla can be calculated from Spherical Trigonometry, using Great Cirlce concept or shortest distance theory, assuming the earth is a sphere. The fact that the earth is a geoid (ellipsoid flattened at the poles) affects ...
How to find magnetic field between two parallel current-carrying wires? A 0.60-T magnetic field is directed perpendicular to the plane of a circular loop of radius 0.40 m. What is the magnitude of the magnetic flux through the loop?
A palm-sized sensor that guides aircraft and spacecraft also has a more down-to-earth application such as helping drilling and mining companies reach diverse oil fields and mineral resources around the world. High-precision accelerometers provide critical acceleration data in all kinds of applications...
Naturally, people have wondered whether pigeons might have a built-in compass—something that would tell them about the direction of the earth’s magnetic (磁的) field. Many different kinds of experiments were done. Here’s what the scientists decided after they had made experiments many times....
