What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
How is electrical energy transferred in a transformer?
It is important to note that that transformer input and output are isolated from one another, in the sense that an electrical charge cannot move from input to output. The energy is transferred via the magnetic field. The alternating current in the input causes a magnetic field; this magnetic field causes an alternating current in the output.
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current

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.
Can DC be used for transformer?
Basis of transformer is change in current. Whenever current flows it causes magnetic field. Current flow in primary coil causes magnetic field around secondary. Since current is changing as in the case of AC, magnetic filed also changes. As per Faraday's law change in magnetic field causes induced voltage at secondary coil. In case of DC there wont be any change in current, thus no change in magnetic field leading to no induced voltage.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
What is an electrical current and what causes it?
Electrical current is nothing but movement of electrons in case of metals. It causes heating and produces magnetic field.

What causes Jupiter's magnetic field?
What causes it's magnetic field is the dynamo effect.

What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Energy conversions - mechanical to electrical?
The usual setup is called a generator. The basic idea here is that a piece of wire moves through a magnetic field; this will cause an electrical current. The electrical current causes another magnetic field that opposes the movement, so it requires (mechanical) energy to keep it moving.The usual setup is called a generator.
