What creates a magnetic field? Magnetic fields are produced by moving charged particles. Even the magnet on your fridge is magnetic because it containselectronsthat are constantly moving around. In an experiment during the early 19th century, it was observed that when an electric current flowed thr...

To address those challenges, the researchers created a “metasheet” that consists of an elastic polymer that is embedded with magnetic microparticles. A pattern was then cut into the sheet. The outer edges of the metasheet are attached to a rigid frame. By moving a magnetic field under the ...
Why doesn't Venus have a magnetic field? Are there southern circumpolar stars? How are magnetic fields created for terrestrial planets? What does the Earth's magnetic field look like? When did Polaris become the North Star? Which of the following correctly describes the meridian in the sky?
It turns out that because the Earth's magnetic field is so weak, a compass is nothing but a detector for very slight magnetic fields created by anything. That is why we can use a compass to detect the small magnetic field produced by a wire carrying a current (see How Electromagnets Work...
Scientists started thinking about this problem by considering the way that electric and magnetic fields were produced in the laboratory. When conductors, like copper wire, move in magnetic fields, electric fields are created. These fields, or voltages, can then drive electrical currents. Thi...
The plasma is trapped within the magnetic fields created in the central section of the system. At each end of the engine are mirror magnets that prevent the plasma from escaping out the ends of the engine too quickly. Of course, you want some of the plasma to leak out to provide thrust...
How are magnetic field lines arranged? What kind of force is magnetism? Why does electricity produce magnetism? How does special relativity make magnets work? How is electromagnetism created? How to produce a uniform magnetic field. How does a magnetic field sensor work?
The communist legacy and the European Union (EU) accession process – what we call the demarcation and integration magnets – created a bipolar magnetic field, in which political parties are aligned on a single axis from one pole bundling left-wing economics and cultural traditionalism to another ...
Magnetic fields are created from electrically charged gases generating electrical currents that act as a magnetic dynamo inside the sun, according to astatement from NASA. These magnetic fields twist, tangle and reorganize themselves due to the turbulent nature of the gases that create them, according...
