Magnetite | SpringerLink
The heating rate is all the more remarkable when one considers that the volumetric specific heat capacity of magnetite is higher than that of most other solids by 50–70%. That means that magnetite has to be much more efficient at adsorbing energy in order to achieve the same temperature compared to other substances.

How can a magnet be demagnetized?
It is also possible to demagnetize a magnet by hitting the ends of the magnet with a hammer, which will alter the order of the magnet. To hit a magnet with an object in general, applying force, is a good mechanism to achieve this objective. In the same way you can also use an alternating current field to alter the order of the magnetic poles.

What is a storage heater and what are the alternatives?
Electric Radiators / Panel Heaters. These would be a good alternative for people who tend to require heating only at certain times of the day. For example, for someone who works 9-5 and requires the heating only in the morning and evening in the week, but more frequently at the weekend, these types of heaters would be ideal. This is due to ...

A good way to store thermal energy is by using a phase-change material (PCM) such as wax. Heat up a solid piece of wax, and it''ll gradually get warmer—until it begins to melt. As it transitions ...
Tips For Storing Canned Food In A Hot Climate | Build a Stash
Here are three tips for storing canned food in a hot climate: Try to keep the cans in the coolest spot possible in your home. Check the expiration dates and rotate cans as necessary. Use aluminum containers over glass containers when you can. Canned goods have been a staple in our homes, restaurants, schools, and business for over one …
Magnetite nanoparticles with high heating efficiencies for application …
As can be seen in Table 1, the in vitro heating efficiency began to decrease from Sample C, which had a mean particle size of 36 nm. Therefore, as shown in Fig. 3, Sample C, which contained some particles greater than 44 nm, showed a slightly lower heating efficiency than Sample B (24 nm).
Magnetite for heat storage informative
While Magnetite has been used for over 30 years to store heat in so-called Night Storage Heaters, it can also benefit industrial applications. This video exp...

What Surfaces Will Magnet Stick To
Magnets will not stick to nonmetal materials — like plastic, wood, cloth, paper, and fiberglass — which you may know from experience. That''s because these materials have low permeability — magnetization generated from an applied magnetic field — and field lines can''t pass through them.
