because, when a steel ship is constructing then there must be a current flow to construct it.as there is a current flow then the steel ship turned into a magnet.because steel is magnetic element.

Is steel a magnet?
Not usually, but it can be magnetised. (=
Why is iron a better core material than steel?
Because steel remains magnetised
Why steel is not used to make electromagnet?
for an electromagnet, you need a core material with low remnance. That is, when you remove the magnetomotive force (current in the coil) the core will (mostly) demagnetise and let the load or armature go. Iron or silicon steel has this property. Other steel alloys do not necessarily have this property. They have a high remnance which means they remain highly magnetised even wjen the mmf is removed. This is an undesirable property for an electromagnet.
What is the use of zinc in its pure form?
Here are a couple of uses. There are more. Steel dipped in liquid zinc is called galvanized steel. The zinc coating prevents rust. A large brick shape of zinc is cast around a steel strap. The strap is then welded to the steel hulls of ships on that part of the ship below the waterline. Galvanic action then eats away the zinc leaving the steel structure undamaged. Zinc is also used as a sacrificial anode in an impressed current type of protection system for buried pipelines.
Can you float a block of steel in water?
Not as long as it's still in the shape of a block. But if you re-shape it into the shape of a cup ... whether round or rectangular ... it will float, because it displaces much more water than a block does. If your cup-shape is done artistically and with care, people may call it what it looks like ... a little "boat" or "ship". Those objects are usually made out of re-shaped blocks of steel.
What is the diffrent between a magnetised steel nail and an unmagnetised steel nail?

Is steel bolt a magnet?
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
Why is iron a better core material than steel?
Because steel remains magnetised
Why is steel attracted to a magnet but not brass?
magnets attract steel why then is a compass needle affected by a pice of steel if the steel is not magnetised
Will a magnetized screwdriver attrat steel screws?
Yes, that is why it's magnetised.
Why is iron better core then steel?
Because I said so Because steel remains magnetised Source: me
Why does a steel ship become magnatised as it is constructed?
Welding, in short. Welding steel which contains iron will magnetize it as running an electric current through it will create a temporary magnetic field. This field will magnetize the iron in the steel and therefore give the ship a field of its own.
Can a steel bar be magnetised by double stroke?
Short Answer: Yes. Long Answer: Yes.
Is a bolt magnetic?
Only if the steel bolt has been magnetised, or is the core of an electromagnet.
Why do steel and iron attract each other?
Metals can be magnetised which can produce an attractive force.
What is the difference between a weakly magnetised nail and a strongly magnetised nail?
The strong magnetised nail will pick up more paper clips than the weak magnetised nail.That is because the strong magnetised nail is getting more strength and that means that the weak magnetised nail is getting less strength.in a steel nail there are these things called domains, in a weakly magnetised nail some of them will be pointing north, south, east and west, but however in a strongly magnetised nail all the domains will point to north.
