Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, and where they can attract or repel other magnets.
New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...
The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Details Equipment [1] Bar magnet [1] Shaker of iron filings [3] ...
Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...
Bar magnets and horseshoe magnets are examples of permanent magnets. Induced magnets Unlike a permanent magnet, an induced magnet close induced magnet A temporary magnet, made from a magnetic ...
Strong magnets can also align the magnetic fields of weaker ferromagnetic materials, making them magnetic. Magnets come in many different sizes, shapes, and strengths. Do you think you can tell how ...
The magnetic field around a circular loop of wire is similar to that of a bar magnet. When an electric current flows through the loop, it generates a magnetic field.
Earth's magnetic field can be visualized if you imagine a large bar magnet inside our planet, roughly aligned with Earth's axis. Each end of the magnet lies relatively close (about 10 degrees) to ...
That magnet is strong, representing roughly 75 percent of the intensity of Earth's magnetic field at the surface. Of course, a bar magnet is not a perfect representation — it's actually electric ...
The other 25 percent of the intensity of Earth's magnetic field, which can be thought of as smaller bar magnets that are moving around, comes from smaller portions of moving magma and may be what ...
Magnets that generate persistent magnetic fields typically are composed of solids like iron, where the magnetic poles of densely packed atoms are all locked in the same direction (SN: 2/17/18, p. 18).
