In reality, the field lines don’t start or stop, but are closed loops like rubber bands, that can bend and stretch when affected by other magnetic fields or materials. This other diagram is a better way to understand the field lines....
As such, much about FRBs remains unknown. Scientists don't know exactly what causes FRBs. Proposed candidates include magnetars, rapidly rotating neutron stars with powerful magnetic fields; merging faint, dense stellar remnants calledwhite dwarfs; collapsing neutron stars, or "blitzars"; and collid...
With stronger magnetic fields, the electronic device advisory must be more stringent. In addition, susceptibility effects are more pronounced, in both chemical shift and field inhomogeneity. In addition, motion degradation is more severe. Plus, hardware availability is limited as some vendors maintain ...
http://www.esa.int/Our_Activities/Observing_the_Earth/Swarm/Earth_s_magnetic_heartbeat The magnetic field is thought to be produced largely by an ocean of molten, swirling liquid iron that makes up our planet’s outer core, 3000 km under our feet. Acting like the spinning conductor in a...
magnetic field and cannot be turned off like electromagnets. Likewise, it is not easy to control the intensity of a permanent magnet’s magnetic field. Furthermore, permanent magnets do not usually have a very large magnetic field, a property that makes it difficult to use them over long ...
Superconducting magnets offer stronger and controllable magnetic fields compared to conventional magnets. They are highly energy-efficient because of zero resistance, which makes them cost-effective for continuous use. Their benefits span medical, research, and transportation fields, including: ...
(around 24 kilometers) in diameter, making them incredibly dense. This means that their gravitational pull is immense, for example, on the surface of a neutron star gravity is around 1 billion times stronger than its pull on Earth. This makes neutron stars a great test subject to challenge ...
magnetic fields. However, in some materials, when you apply a magnetic field, the spins of neighboring electrons align with one another, which produces a net field across the whole material. In short, instead of cancelling each other's fields, the electrons in these materials join together and...
makes each atom a tiny magnet within a larger magnet. These tiny magnets are called dipoles because they have a magnetic north and south pole. Individual dipoles tend to clump with other dipoles forming larger dipoles called domains. These domains have stronger magnetic fields than individual ...
I actually think one of the most common uses of magnets these days is to take money off people. There are all kinds of health claims about magnets that have never been proved, but people will spend a lot of money trying to reap the benefits from a magnetic force field or something. ...
