Current flows through a wire and produces a magnetic field.
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
Yes, by moving the conductors through the magnetic field.
The lines that map out the magnetic field around a magnet are called magnetic field lines. These lines indicate the direction of the magnetic field and its strength at different points around the magnet. Magnetic field lines are closest together where the magnetic field is strongest and they form closed loops that do not intersect.
Electrons have a charge. Any moving charge creates an electric field, e.g. electricity moving through a wire causes a magnetic field around the wire, or the earth rotating creates a magnetic field which causes a compass to point north. Similarly all electrons have a spin factor. similar to the earth rotating, the spin of electrons create a magnetic field around the electron.
No. The magnetic field is produced by currents in Earth's outer core, which is composed largely of molten iron.
Magnetic field.
A magnetic field is produced by moving electric charges. When electric charges move, they create a magnetic field around them. This magnetic field can interact with other magnetic fields and cause objects to be attracted or repelled.
Earth's magnetic field is produced by the dynamo effectin the liquid metal outer core.
A permanent magnet can create a magnetic field with no current. This is due to the alignment of the magnetic domains within the material, which results in a net magnetic field. The magnetic field produced can attract or repel other magnets or magnetic materials in its vicinity.
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
A magnetic field is produced around a wire when an electric current flows through it. This magnetic field is directed along circular lines around the wire.
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.
A magnet has a magnetic field around it. The magnetic field causes a magnetic force that can attract objects to the magnet.
When copper wire is wrapped around a magnet, it creates an electromagnet. This increases the strength of the magnetic field produced by the magnet.
When an electrical current flows through a wire, it creates a magnetic field around the wire.
By passing a current threw it.
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.
