Why electric not attract iron objects when current is passed through it?

Any electric current does generate a magnetic field, but it might be a very weak
magnetic field that you would not notice. In order to create a powerful electromagnet,
wire is wrapped around a ferromagnetic core, typically hundreds or thousands of times.
Each coil of the wire adds to the magnetic field. But unless the current is extremely
strong, a single straight wire produces a magnetic field that's quite weak, but it IS
strong enough to deflect a nearby magnetic compass.

Why does a metal spring contract when an electric current is passed through it?
due to magnetic fields produced which attract each other since parallel current carrying conductors attract each other
A complete path for electricity to flow?
currents can be thought of simply by flowing through a wire, though not always the case. It is convenient to think of current density which is the amount of current flowing through a cross sectional area, like water through the opening of a pipe, since electric current flows through many 3-dimensional objects.
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
The flow of electrons through a conductor is called?
electric current
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
Why steel becomes a permanent magnet after electric current is passed through it?
Electric current is magnetic so when electric current pass through steel , steel will have the electric power and may be magnetic for awhile
If the electrons and protons attract in what way is it dangerous for you to stand under a tree when there is lightning?
The fact that electrons and protons attract has little if anything to do with lightning or why it is dangerous. Lightning is a huge burst of stored electric charge. That charge becomes a very high current through the air, but electric current prefers to go through things like water and metal, because it's less resisitive than air. This means that trees are more likely to get hit by lightning (as are other tall objects like churches and buildings). So, standing under one means it is quite possible you will get hit by the lightning too.
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What kills you when you get an electric shock?
electric current through your nerves and/or muscles, especially through your heart
When an electric charge moves through a conductor there is an electric in the conductor?
current
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
