Passing an electric current through a wire will produce an external magnetic field.
This is because the electrons have spin and this spin is what produces the field.
Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets.
And no spinning electrons, no magnetic field.
What else can I help you with?
What is produced around a wire that has a current?
Magnetic field.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
Moving a wire through a magnetic field does not create a current flow in a wire?
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
What is the direction of the magnetic field if the current is directed upward or downward?
The direction of the magnetic field is counterclockwise or clockwise. For a current flowing in a wire you can use the "left hand rule" If you take your left hand and have the thumb point in direction of electron flow in the wire, the fingers wrapped around the wire will show the direction of the magnetic field by the direction the fingers are pointed..
The combination of the magnetic field of the coiled wire and the iron create a very what magnet?
The combination of the magnetic field of a coiled wire wrapped around an iron core will create a very useful electromagnet. This is the bases used in the construction of mechanical relays.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
With the use of unshielded twisted pair copper wire in a network what causes crosstalk with the cable pairs?
the magnetic field around the adjacent pairs of wire
How does electricity create a magnetic field?
When electricity flows through a wire, it creates a magnetic field around the wire. This is because the moving electric charges generate a force that causes the magnetic field to form.
Does electricity flow through wire or around its magnetic field?
Eiectricity flows through wire not around the magnetic field.
What is produced around a wire that has a current?
Magnetic field.
When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)
What is the magnetic field around a wire when the current running in the wire is in reverse direction?
The magnetic field around a wire is determined by the direction of the current flow. If the current running in the wire is in the reverse direction, the magnetic field around the wire will also be reversed. The direction of the magnetic field is determined by the right-hand rule, where if you wrap your right hand around the wire with your thumb pointing in the direction of the current, your fingers will point in the direction of the magnetic field.
Which of following would decrease the magnetic field around a wire?
Inserting a material with a high magnetic permeability around the wire or reducing the current flowing through the wire would decrease the magnetic field around the wire.
Does a wire with no current have a magnetic field?
Yes, a wire with no current flowing through it does not produce a magnetic field. Current flow is required to generate a magnetic field around a wire.
What happens to a current-carrying wire when placed in a magnetic field?
When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the electric current. This force causes the wire to move or experience a deflection, depending on the orientation of the wire and the magnetic field.
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
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.
What happens to a current carrying wire in a magnetic field when it is reversed?
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
