When a compass is placed near an electric outlet why does it move?

Electric current produce magnetic fields. However, in the case of AC (alternating current, usual in households), the current changes so quickly (and the current has an average value of zero) that I am not sure the effect on a compass would be visible to the naked eye.

Why does a compass needle move when placed near a wire carrying an electric current?
True... The wire carring current creates a slight magnetic field.
Why does the needle on a compass move when placed in the coil of wire?
It moves because it wants to have compass babies with raccoons and so it won't get high it move and that is it giving birth
How does a compass needle move when it is placed in a magnetic field?
A compass needle aligns itself with the magnetic field lines and points toward the magnetic north pole. The north-seeking end of the needle is attracted to the Earth's magnetic south pole, causing it to move and orient itself accordingly.
How did Oersted discover the relationship between an electricity and magnetism?
He used an electric current to affect the needle of a compass.
What happens when an electric field is placed inside a magnetic field?
Electricity is formed (electrons move )
How magnet in compass work?
The magnet in a compass is free to move, and will adjust to any external magnetic field.The magnet in a compass is free to move, and will adjust to any external magnetic field.The magnet in a compass is free to move, and will adjust to any external magnetic field.The magnet in a compass is free to move, and will adjust to any external magnetic field.
Does electric currents cause coils in magnetic fields to move?
yes, electric feilds do cause the magnetic feilds in the coils, this was first observed by Hans Oersted in 1819. He showed that when an electric current was passed theough a wire a nearby compass needle showed a deflection, this prooves that an electric feild causes an magnetic feild.
When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.
What is the srtongest electric move?
the strongest electric type move is volt tackle
Which test can best detect the presence of electrical current a the needle of a compass b the bulb in an electric circuit blows c the plug of an iron is placed in the socket?
Here are some possible answers: a) If you hold a compass close to a wire you may see the needle move. How much it moves depends on the strength of the current flowing in the wire. If the needle doesn't move then there may be three explanations: 1) No direct current was flowing in the wire OR 2) a direct current was flowing but it was too weak to make the compass needle move OR 3) there might have been a current but it was an alternating current changing so fast that the needle did not seem to move. b) If the bulb in an electric circuit was lit but then blows, it may mean one of two things 1) the current was switched off so the bulb went out OR 2) the bulb just died, in which case any current that was flowing in the bulb's circuit would stop. c) when the plug of an iron is placed into a socket, if it warms up then a current must be flowing from the socket to the iron. But before the iron was plugged-in, no current was flowing. Now you work out which of those answers to this question is the right one!
How does the fixed foot of the compass move?
It leans toward the other foot.
How can it be shown that a magnetic field exist around a wire though which a direct electric current is passing?
The magnetic field can easily be detected with a permanent magnet that is free to move - for example a compass (which has a magnetic needle), or a magnet hanging on a string.
