A bird sitting on the wire flies away if a high voltage is passed through the wire?
Not so. We see birds sitting on active high lines all the time.
What is Elctromagnetic?
An electromagnet is created by winding a coil of wire around an iron core. Electrical current is passed through the wire, which creates a magnetic field. Something that is electromagnetic is anything that is an electromagnet.
Why the temp of metallic wire rises when a current passes through it?
When current is passed through the wire, the negatively charged electrons (Current) face resistance as the molecules of the conductor block their way. These moving electrons collide with the molecules of the conductor and heat is produced which heats up the metallic wire.
When a magnet is moved alongside a wire what happenes?
the electrons in the wire begin to flow
What are the interactions between magnetic objects and electrical circuits?
Magnets actually generate electricity. When a wire is passed through a magnetic field it produces electron flow. Coils of wire can detect magnetic flux variation and be used as sensors.
What shape is the magnetic field produced when current is passed through wire?
CIRCULAR
Is copper wire is magnetic?
it produces a magnetic field. i think that if current is passed through the wire it can attract pieces of iron
How is electricity transferred from batteries to the light bulb?
Electricity is passed through a wire from battery to bulb
When a current is passed through a coil of wire what forms Is it A. an electromagnet or B. A commutator?
a magnetic field
What happens when electric current is passed through Cu wire?
as a cu wire is a conductor, electrical current does go through it, but some of the electrical energy gets converted into heat energy, and that is why the wire aslo heats up a bit.
What is made by passing an electric current through coils of wire?
An electro magnet is created when a current is passed through a coil of wire. This effect is the main operation of how an electrical solenoid operates.
Does nichrome wire get red hot when current is passed through it?
Yes ,due to heating effect of current.
When does an electromagnet produce a field?
An electromagnet produces a magnetic field when current is passed through it wire winding.
A bird sitting on the wire flies away if a high voltage is passed through the wire?
Not so. We see birds sitting on active high lines all the time.
When DC is past throgh coil of wire what is formed?
When a current is passed through coiled wire, the wire will store some of that energy in a magnetic field. As soon as the source of the current is removed, the engergy in the magnetic field will return to the wire.
If the current running through a wire is 1.2 amperes and it passed through a resistor of 7.5 Ohms what is the voltage of the system?
9V by using ohms law
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
