Is aluminium better than iron to make an electromagnet?

Answer 1

trytrytrytrytrytry says iron is magnetic

where as steel ios a compound??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

will you eat me??

Answer 2

Ordinary steel is not so effective as soft iron because its permeability is lower. Special steel for electromagnets and transformer cores can be made.

Electrical steel, also called lamination steel, silicon electrical steel, silicon steel or transformer steel, is specialty steel tailored to produce certain magnetic properties, such as a small hysteresis area (small energy dissipation per cycle, or low core loss) and high permeability. The material is usually manufactured in the form of cold-rolled strips less than 2 mm thick. These strips are called laminations when stacked together to form a core. Once assembled, they form the laminated cores of Transformers or the stator and rotor parts of electric motors.

Answer 3

It is desirable in an electromagnet that the magnetic field will cease when the current flowing through the electromagnet coils stops. If steel is used there is still some residual magnetism when there is no current through the coils. This is an unwanted effect. On the other hand when soft iron is used the magnetic field vanishes when the current stops.

Answer 4

Both aluminum and iron can be used to make electromagnets, but iron is generally preferred due to its higher magnetic permeability, which allows it to create a stronger magnetic field. Aluminum has lower magnetic properties compared to iron, so it may not be as effective in creating a strong electromagnet.

Answer 5

yes,aluminium is better than iron to make electromagnet because aluminium posses good thermal expansions.

Answer 6

Yes, one of the best.

Answer 7

Yes, very much so.

Answer 8
