A Magnetic base works using a powerful magnet and three metallic plates.
Out of the three plates, two of them are made of Iron ( para magnetic i.e. attracted by a magnet) and the third one is made of a non para-magnetic (for example Aluminum).
The plates are made so that they make a cylindrical housing in the center in a way that the Iron plates surround the Aluminum plate.
The magnet is made of a cylindrical shape with the North and South poles on its length not on its faces(on its circular face, to understand draw two lines form top to bottom on a glass each on the opposite side.
Now when you turn the KNOB, you rotate the magnet so that the poles come in contact with the Iron plates and the base becomes magnetized.
and to de-magnetize, the KNOB is turned to make the poles face the Aluminum plate.

Pure nickel is magnetic at/or near room temperature but above and ceasses to have this property above 355°C. Nickel base superalloys are used in ultra critical components of aero engines where magnetism will be detrimental,so be rest assured nickel base superalloys are not magnetic.
They could be if you have magnetic powers
Yes, the magnetic field is a non-conservative field. This means that the work done by a magnetic field on a charged particle moving in a closed path is generally not zero, unlike a conservative field where work done in a closed path is zero.
Yes, iron is a ferromagnetic material, meaning it can be magnetized and exhibit magnetic properties. When iron is brought into contact with a magnetic field, its atoms align to create a magnetic field, allowing it to be attracted to magnets and exhibit magnetic behavior.
No, wood is made of mostly non-magnetic elements. copper, aluminium, gases, and plastic are also non-magnetic. The influence of a magnetic field on wood is not significant; however all elements are influenced by magnetic fields or electro-magnetic waves to some extent. That influence is significant on only few elements, such as iron.

Why not? the desert is just the same as any other place on planet earth. Magnetic compasses work fine in the desert. See the "Where does the magnetic compass not work?" question for some places where they don't work.
They work by using a magnet.
There are still magnetic fields in space - especially if you remain close to Earth. But magnetic compasses are usually designed to use gravity, which you won't have if you are in free fall. A specially-designed magnetic compass would work, though.
No, the sun does not have an iron core to generate magnetic poles
Some piggy banks may have a magnetic feature to help secure coins in place, but not all piggy banks are magnetic. Magnetic piggy banks are designed with a magnetic base that attracts metal coins to keep them in place.
Silver plated objects are typically not magnetic because silver is a non-magnetic metal. If the base metal beneath the silver plating is magnetic, such as iron or steel, then the object may exhibit some magnetic properties.

yes it can.
No, a static magnetic field cannot do positive work on charged particles. Magnetic fields can only do work on moving charged particles by changing their directions of motion or causing them to spiral. Static magnetic fields do not affect stationary charged particles.
How do magnitized car crushers work?
Magnetic force does not do any work because it acts perpendicular to the direction of motion of the charged particle. Work is defined as force acting in the direction of motion, and since magnetic force acts perpendicular to the motion, it does not transfer energy to the particle in the form of work.
