A current flowing through a wire produces a magnetic field around the wire. The direction of the magnetic field is determined by the right-hand rule, where if you point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines. The strength of the magnetic field is directly proportional to the current flowing through the wire.

What is produced around a wire that has a currrent?
When a current flows through a wire, a magnetic field is produced around the wire. This magnetic field is perpendicular to the direction of the current flow and its strength is proportional to the amount of current flowing through the wire.
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.
In a solenoid, will there be a magnetic field if there is no current flowing through it?
Yes, a solenoid will still have a magnetic field even if there is no current flowing through it.
What happens when a current stops flowing through the wire of an electromagnet?

What are three ways you can change the magnetic field produced by a current?
You can change the magnetic field produced by a current by altering the strength of the current flowing through the conductor, changing the direction of the current flow, or varying the distance between the conductor and the point where you are measuring the magnetic field.

What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.

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 strength of an electromagnetic field when you increase the current flowing through the coil of wire around an iron bar?
Increasing the current flowing through the coil of wire around an iron bar will increase the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
How may a coil carrying current increase magnetic flux density?
Increasing the current flowing through the coil will increase the magnetic field produced by the coil, which in turn will increase the magnetic flux density inside the coil. This relationship is described by Ampere's law which states that the magnetic field is directly proportional to the current flowing through the coil.
How does increasing the voltage of a supply in a electromagnet affect the strength of the magnetic field?
Increasing the voltage of a supply in an electromagnet increases the current flowing through the coil, which in turn increases the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
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.
Electrical current produced by water flowing through a turbine?
The electrical current produced by water flowing through a turbine is generated through electromagnetic induction. As the water flows through the turbine and causes it to rotate, the rotating turbine interacts with a magnetic field, inducing an electrical current in the surrounding wires. This current can then be harnessed and converted into usable electricity.
