yes it does the current flows in a wire it creates a magnetic field around the wire.

Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.
Why are insulators of electricity used to prevent electric shock?
Because they prevent the electric current from passing through them and damaging the human who touched the source or another piece of electronics.
Does the metal need to be an certain size or length for an electromagnet?
You can make any metal piece of any size an electromagnet by wounding a conducting wire around it and passing an electric current through it....
What is a piece of clear glass or plastic that bends light rays passing through it?
It's a prism. A prism splits the light up in all color's of the rainbow.
An electromagnet is a solenoid with a piece of ferromagnetic material within it?
Yes.

How do you prove the object is magnetise?
hold a piece of iron or magnesium up to it and if it attracts it is magnetic

Glass.reflection

What is the principle of electromagnetism?
pricinples of electromagnetism state that when current passes through a piece of wire magnetic field is generated around the piece of wire and when a piece of wire passes through the magnetic field current is induced into the piece of wire
What is the three principle of electromagnet?
pricinples of electromagnetism state that when current passes through a piece of wire magnetic field is generated around the piece of wire and when a piece of wire passes through the magnetic field current is induced into the piece of wire
Which separationtechnique is used to separate Small piece of metal in the engine oil of a car?
It can be either the passing of the oil through a filter system, or the passing of the oil through a magnetic system, or a combination of both.
A short piece of metal that melts when a large current passes through it is a?
Fuse
Electric current that moves through a coiled wire wrapped about a piece of iron creates?
Magnetic field.
How do you magnetise a magnetic material?
you can only magnetize something that contains iron. if what you have contains iron, then you rub a magnet on it
Applications of insulating materials in electrical field?
this stops current from passing between two pieces of the circuit, for example, there is a piece of Dieletric in a capacitor, this is so current cannot travel between the two separate plates, and if there is no current between a positive and a negatice plate then there is not electrical field
