In a current carrying conductor what exist around it?
a magnetic field
Created around a conductor when electrons flow through that conductor?
Then an 'electrical current' is said to be present in the conductor.
What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
Is aluminium magnetic when a current is passed throu it?
When current flows through any conductor, there is a magnetic field around the conductor. It doesn't matter what substance comprises the conductor. I guess that means that aluminum wire can be an electromagnet, but not a permanent one.
A current flowing towards the viewer in a cross section conductor is shown by?
Sketch the direction line of force around a conductor which is carrying current away from the viewer and also towards the viewer.
How do tongtester is working?
Tong tester is an electrical device having two jaws that allow clamping around an electrical conductor. It helps to measure the electric current in the conductor.
What type of accessory device can be used to measure AC with a VOM without opening the circuit?
Electricians use a clamp or clamp-on ammeter to measure current. The handles are squeezed together and the "jaws" open up. The clamp is then slipped over the conductor and the handles are released. The "jaws" close around the conductor and the meter is then in a position to measure current in that conductor. When current flows in a conductor, the current generates a magnetic field around the conductor. And the clamp-on ammeter can "feel" the current and measure it, thus permitting an investigator to know how much current is flowing in that conductor. The clamp-on ammeter is a stand-alone meter, but can sometimes be the kind that is plugged into a digital multimeter (DMM). A link to the Wikipedia article on the clamp ammeter is provided.
In a current carrying conductor what exist around it?
a magnetic field
What is the Field due current flow through a conductor?
Circular magnetic field will create around the conductor.
How can you use clamped in a sentence?
He clamped his hand tightly around the paper.
Created around a conductor when electrons flow through that conductor?
Then an 'electrical current' is said to be present in the conductor.
What is the relationship between magnetic fields and electricity?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
What is formed around a conductor when a current is passed through it?
A magnetic field.
How electric current causes magnetic field around conductor?
Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.
What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?

Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?
This proves that a magnetic field is developed around the conductor wen current flows through it...
