An electric current flowing through a wire gives rise to a magnetic field whose direction depends upon what of the current?
The direction of the magnetic field produced by an electric current flowing through a wire is dependent on the direction of the current. The right-hand rule can be used to determine the direction of the magnetic field relative to the direction of the current flow.
What happens to the direction of a magnetic field around an electric current when the direction of the current is reversed?
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
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.
Why does a compass change direction when it is near a current-carrying wire?
A compass needle is deflected when placed near a current-carrying wire due to the magnetic field generated by the flow of electric current. The magnetic field produced by the current interacts with the Earth's magnetic field, causing the needle to align in a different direction.
What type of magnet is produced by an electric current?
An electromagnet is produced by an electric current. When an electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.

What is a temporary magnet produced using an electrical current?
A temporary magnet produced using an electric current is an electromagnet. When an electric current flows through a coil of wire wrapped around a magnetic core, such as iron, it generates a magnetic field. This magnetic field allows the electromagnet to attract and hold magnetic materials like iron or steel.
How do you reverse the direction of a magnetic field?
You can reverse the direction of a magnetic field by changing the direction of the electric current flowing through a conductor. This is known as the right-hand rule - if you pass your right-hand thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field. By reversing the direction of the current, you can reverse the direction of the magnetic field.
How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
What is the right hand rule for current in a wire and how is it applied to determine the direction of the magnetic field produced by the current flow?
The right-hand rule for current in a wire states that if you point your right thumb in the direction of the current flow, then the direction your fingers curl around the wire represents the direction of the magnetic field produced by the current. This rule helps determine the relationship between the direction of current flow and the resulting magnetic field around the wire.
If the current in a wire is directed upward what is the direction of the magnetic field produced by the current?
The magnetic field produced by a current-carrying wire points in a circular direction around the wire, following the right-hand rule. In this case, with the current directed upward, the magnetic field would circle around the wire in a clockwise direction when viewed from above.
