Magnetic in sentence

208 examples of Magnetic in a sentence

Instead, it is recorded as a magnetic pattern formed by groups of those tiny grains.
Once this information is written onto the disc, the drive uses a magnetic reader to turn it back into a useful form, much like a phonograph needle translates a record's grooves into music.
And despite its size, the reader became more sensitive by taking advantage of new discoveries in magnetic and quantum properties of matter.
Bits could also be packed closer together thanks to mathematical algorithms that filter out noise from magnetic interference, and find the most likely bit sequences from each chunk of read-back signal.
And thermal expansion control of the head, enabled by placing a heater under the magnetic writer, allowed it to fly less than five nanometers above the disc's surface, about the width of two strands of DNA.
But at around 100 gigabits per square inch, shrinking the magnetic grains further or cramming them closer together posed a new risk called the superparamagnetic effect.
When a magnetic grain volume is too small, its magnetization is easily disturbed by heat energy and can cause bits to switch unintentionally, leading to data loss.
Recently, the potential limit has been increased yet again through heat assisted magnetic recording.
This uses an even more thermally stable recording medium, whose magnetic resistance is momentarily reduced by heating up a particular spot with a laser and allowing data to be written.
Other promising treatments, like transcranial magnetic stimulation, are being investigated, too.
Electromagnetic radiation is pure energy consisting of interacting electrical and magnetic waves oscillating through space.
In magnetic storage, which is the cheapest, data is stored as a magnetic pattern on a spinning disc coated with magnetic film.
While optical storage media are cheap and removable, they have even slower latencies than magnetic storage and lower capacity as well.
Now, one summer day in 2006, she was at a dig site called the Fyles Leaf Bed, which is less than 10 degrees latitude away from the magnetic north pole.
These elements have a huge range of magnetic, phosphorescent, and conductive properties that make them crucial to modern technologies.
You know, the force responsible for electricity and magnetic attraction and so forth.
In that way, it starts rotating very fast and it increases, powerfully, its magnetic field.
The matter around the star is dragged around, and some energy from that rotation is transferred to that matter and the magnetic field is increased even further.
And just for your information, the magnetic field of a magnetar is 1,000 trillion times the magnetic field of Earth.
You may remember that we were talking about a super-massive star that became a very strong magnetic field magnetar.
Magnetic fields are generated in the deep interior of a planet by electrically conducting churning fluid material that creates this big old magnetic field that surrounds Earth.
Many scientists think that a magnetic field of a planet serves as a shield for the atmosphere, deflecting solar wind particles around the planet in a bit of a force field-type effect having to do with electric charge of those particles.
OK, so the effect, then, is that Earth may have been protected for billions of years, because we've had a magnetic field.
Mars, on the other hand, has been unprotected because of its lack of magnetic field, and over billions of years, maybe enough atmosphere has been stripped away to account for a transition from a habitable planet to the planet that we see today.
Other scientists think that magnetic fields may act more like the sails on a ship, enabling the planet to interact with more energy from the solar wind than the planet would have been able to interact with by itself.
The magnetic field may gather energy from the solar wind that allows even more atmospheric escape to happen.
That energy is conducted along magnetic field lines down into the polar regions, resulting in incredibly beautiful aurora.
We're trying to measure how many particles are getting out and if the magnetic field is influencing this in any way.
And we can decide whether magnetic fields are important for habitability or not.
Tel Aviv and Abu Dhabi are talking about testing these futuristic networks of suspended magnetic pods.
