Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A magnet is attracted to a soup can because the can has
A
a South pole.
B
a North pole.
C
a magnetic field.
D
iron in it.
Explanation: 

Detailed explanation-1: -Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnetic field of a magnet, the polarization of the iron s atoms is random.

Detailed explanation-2: -Magnetism. Iron, steel, tin and aluminum are paramagnetic materials–so regardless of the composition of your “tin” can, it will be attracted to a magnet.

Detailed explanation-3: -Magnetic fields will pass through plastic, wood, aluminium and even lead as if it was not there. There is no material that will block magnetism. Ferrous materials such as iron, steel or nickel can conduct magnetic fields and redirect magnetism.

Detailed explanation-4: -Most permanent magnets contain iron, nickel, or cobalt. Alnico is an alloy made up of aluminium, nickel and cobalt. A strong permanent magnet can be made from Alnico alloys. Consumer electronics and industrial applications use them extensively.

Detailed explanation-5: -When you bring a magnet near a piece of iron, the iron-atom magnets line up with the applied magnetic field: The north poles of the iron atoms all point in the same direction. Because the iron atoms line up, the piece of iron becomes a magnet and is attracted to the original magnet.
