Demagnetization works by removing the magnetic field from a magnetized object so they no longer attract metal. Most magnets can be demagnetized temporarily or permanently.

Does aluminum protects against demagnetization?
No it does not , the first thing we should think of is that aluminum is non magnetic
What are the ways to prevent demagnetization of magnets?
By keeping them in magnet keepers
Why ferromagnetic substances are not used in adiabatic demagnetization?
A system that is a perfect ferromagnet has all the spins aligned whether or not there is an external magnetic field. As a result applying an external magentic field does not change the spin configuration at all, and does not change the entropy at all. Therefore this will not change the temperature.
How does the use of keepers help eliminate self-demagnetization in the storage of magnets?
Magnetic keepers can be thought of as materials that complete the magnetic circuit of the magnet. They do this by providing a paramagnetic link from one pole of the magnet to the other. That way the magnet can resist the effects of other magnetic fields that might tend to depolarize or demagnetize it.
What is hysteresis calibration loop?
In hysteresis materials it represents the energy dissipated in them during the cycle of magnetization & demagnetization (just refer any hysteresis loop diagram) . This is used in many applications especially in aerospace to damp the oscillations in satellite.
What are the methods of demagnetization?

How do train brakes work?
Eddy current.(based on the concept of magnetization and demagnetization)
What is the process called when a magnet loses it's magnetisim?
Demagnetization

What is the significance of looping?
In hysteresis materials it represents the energy dissipated in them during the cycle of magnetization & demagnetization (just refer any hysteresis loop diagram) . This is used in many applications especially in aerospace to damp the oscillations in satellite.
What is magnetic hardness?
Magnetic hardness is the resistance to demagnetization. It is an intrinsic solid state property that is quite in contrast with hardness based on the presence of fine particles.
What has the author D W Emerson written?
D. W. Emerson has written: 'Magnetic exploration models, incorporating remanence, demagnetization and anisotropy HP 41C handheld computer algorithms' -- subject(s): Magnetic prospecting, Data processing
How do you reach absolute zero?
You don't. The current record low temperature is about 100 pK (that is, 0.0000000001 K) which is reached by a process called adiabatic demagnetization, which I'm not even going to TRY to explain here; see the Wikipedia article I've linked to if you want details.
