What is A magnetic substance can also be made into a?
If you are talking about a non-magnet item then the item will become a magnet for a period of time. Changes in heat, how much it is used, or time can disable the magnet. Magnet!
Who discovered magnetic striping on the ocean floor?
The US Navy in the post World War 2 period while trying to improve maps of magnetic anomalies. They kept this information highly classified for decades to prevent the USSR or red China from using it against us should a war start. But this also kept the information away from scientists, delaying the development of the theory of plate tectonics.
What do the moving electrons in a wire produce?
An electric current produces a combination of three effects. These are the heating effect, the chemical effect, and the magnetic effect.The unit of measurement of current, the ampere(A), cold be defined in terms of any of these three effects. However, in SI, the ampere is defined in terms of its magnetic effect -i.e. the force of attraction or repulsion created by the magnetic fields surrounding two, parallel, current-carrying conductors. Prior to its present definition, current was defined in terms of its chemical effect -i.e. the amount of silver deposited by electrolysis over a given period of time.
What is Neptunes period of revolution?
To revolve once around the Sun takes Neptune almost 165 Earth years (164.79 years).Because Neptune is not a solid body, its atmosphere undergoes differential rotation. The wide equatorial zone rotates with a period of about 18 hours, at the polar regions the rotation period is 12 hours. Its magnetic field rotates in 16H 6 MIN 36 SEC. Its orbit around the sun (Neptunian Year) is 60,190 earth days or about 164.79 earth years.
Do the earth's magnetic poles have reversed themselves?
Yes, in the history of Earth, it has happened a handful of times. When it switches we experience what we call a pole reversal. Right now Earth is currently in the process of a pole reversal (the South Pole is moving northwards).
Are ferrets induced ovulators?
Jills are induced ovulators or ovulation is induced by mating. If mating does not occur, and the Jill (female ferret) remains in heat for long period of time, it can lead to serious illness.
Why doesn't iron act like a magnet?
Great question. The Earth has a magnetic field but it is not strong enough to overcome the other forces affecting pieces of iron. But if you wanted to make a super-accurate weighing scale, you would avoid iron for its hanging parts. And every steel can in your kitchen is magnetized from sitting in the Earths magnetic field. Put a compass needle close to a can of beans and see!
How can magnetism be induced in non-magnetic iron?
In a magnetic material that is not a magnet, magnetic domains are arranged in random fashion canceling the net magnetic field. If such a material, like an iron rod, is exposed to a strong magnetic field, the domains will arrange themselves in the direction of the applied field and hence object will become magnetized.
How was the cretaceous period different from the the present?
The main difference is that there were dinosaurs in the Cretaceous Period. Also, the climate was very different and the continents were aligned in different ways.
Why does the number of sunspots vary?
The number of sunspots depends on the magnetic field of the Sun. This magnetic field changes with a period of roughly 22 years; twice in each of these magnetic cycles there is a maximum of sunspots. (So, the sunspot cycle has a period of about 11 years (on average), whilst the magnetic cycle has a period of about 22 years.)I am not sure whether the reasons for the magnetic cycles are completely understood, but you can check what is known so far, in the Wikipedia article on "Solar dynamo".
How long do epochs last?
Magnetic epochs last a long period of time, geologically. It is when the earth's magnetic field is the same polarity.
What is a trip?
A trip is a journey or excursion, a stumble or misstep, or a period of time in which one experiences drug-induced hallucinations.
Who is in charge of giving out a domain name?
No single organization is responsible for 'giving out' domains. Domains aren't 'given out', they're registered for a period of years through an ICANN accredited registrar for most domains used in North America, and by the regional authority in the country for country code domains. Domain Name Registrars own the domains and 'give them out', but for a price. These registrars handle the Domain Name Services functions that turn a domain name into the address of a computer where a website or e-mail is available.
What is exercise induced amenorrhea?
Amenorrhea is when the period is gone for other reasons than pregnancy and in this case too much exercise.
What are the names and symbols of two magnetic elements from the same period?
Period 4: iron (Fe), cobalt (Co), nickel (Ni).
Explain the differences between blacking and passing out?
Passing out is a chemically- induced coma. The person becomes unconscious for a period of time and (hopefully) wakes up eventually.A blackout is alcohol-induced amnesia. The person is unable to remember things that happened when he or she was awake and functioning.
What if you developed amenorrhea after depo and period was induced?
If you induce vaginal bleeding after having Depo-related amenorrhea, you bleed from your vagina. It does not "jump start" your normal period, it doesn't mean you ovulated, and it doesn't get Depo out of your system faster.
