What is an item in which magnetic domains can be aligned and magnetic field induced for a short period of time?
An item in which magnetic domains can be aligned and a magnetic field induced for a short period of time is a ferromagnetic material, such as iron. When exposed to an external magnetic field, the magnetic domains within the material temporarily align, allowing it to exhibit magnetism. Once the external field is removed, the domains may return to a random orientation, causing the magnetism to dissipate. This property makes ferromagnetic materials useful in applications like temporary magnets and magnetic storage devices.

What is A magnetic substance can also be made into a?
A magnetic substance can also be made into a magnet by aligning its magnetic domains in the same direction. This alignment creates a magnetic field around the substance, allowing it to attract or repel other magnetic materials. The strength of the magnet depends on the material and the alignment of its domains.
What is a magnetic period?
A magnetic period is a specific duration of time during which the Earth's magnetic field undergoes reversals, where the magnetic North and South poles switch places. These reversals occur over thousands of years and are recorded in rocks and sediments as a series of stripes of alternating magnetic polarity.
What is exogenous dormancy?
Exogenous dormancy refers to a period of dormancy induced by external factors such as environmental conditions like temperature or humidity. This type of dormancy is not inherent to the seed itself but is a response to external stimuli.
What do you call a magnet that only lasts a short time?
A temporary magnet is a magnet that only retains its magnetism for a limited period before losing its magnetic properties.
What is interesting about Jupiter's rotation period?
Jupiter has a very fast rotation period of about 10 hours, making it the fastest rotating planet in our solar system. This rapid rotation causes the planet to have a squished appearance at its poles and a bulging equator. Jupiter's rotation period also influences its strong magnetic field and intense atmospheric activity.
What is the best procedure to create a permanent magnet?
The best procedure to create a permanent magnet is to expose a ferromagnetic material to a strong magnetic field for an extended period of time, aligning the magnetic domains within the material to create a permanent magnetic field.
How can a magnet be temporarily magnetized when attached to a permanent magnet?
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
What is A magnetic substance can also be made into a?
A magnetic substance can also be made into a magnet by aligning its magnetic domains in the same direction. This alignment creates a magnetic field around the substance, allowing it to attract or repel other magnetic materials. The strength of the magnet depends on the material and the alignment of its domains.
How do you magnetize a piece of metal effectively?
To magnetize a piece of metal effectively, you can rub a magnet along the metal in one direction multiple times. This process aligns the magnetic domains within the metal, creating a magnetic field. Alternatively, you can expose the metal to a strong magnetic field for a period of time to induce magnetization.
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!
What is a magnetic period?
A magnetic period is a specific duration of time during which the Earth's magnetic field undergoes reversals, where the magnetic North and South poles switch places.

How can magnetism be induced in non-magnetic iron?
Iron can be demagnetised by heating for an extended period of time. _______________________________________________________________ You have to melt it and and allow it to re-solidify and it will be demagnetized. If you heat it to near melting and allow it to stay that hot for awhile then it will demagnetize of time (this is because bits of it will be hot enough to melt and demagnetize and that heat will disperse somewhere else to demagnetize a different spont). The temperature at which a ferromagnetic material, which is a material that retains an applied external magnetic field (like iron), loses its magnetization is called the Curie temperature.
Does temperature affect the strengh of a magnet?
Yes, temperature can affect the strength of a magnet. Generally, magnets become weaker as temperature increases. This is because the increased temperature causes the atoms within the magnet to move more vigorously, disrupting the alignment of magnetic domains.
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 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.
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.
