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 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
What is produced around a wire that has a current?
Magnetic field.
Does electricity flow through wire or around its magnetic field?
Eiectricity flows through wire not around the magnetic field.
A current in a long straight wire produces a magnetic field. These magnetic field lines?
The magnetic field lines are arranged circularly around the wire.
How do you know when a wire has current flowing through it?
You can measure with a multimeter. Alternately, you can check for a magnetic field around the wire.You can measure with a multimeter.

Electricity running through a wire will induce field?
A magnetic field around the wire.
How will you describe the magnetic field around a straight current-carrying wire?
the magnetic field gets stronger with increasing distance from the wire
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.
How does coiling a wire affect the magnetic field generated an electromagnet?
Coiling a wire increases the magnetic field of an electromagnet because the magnetic field around a wire is circular and perpendicular to the wire. Each turn of the wire reinforces the field of the one next to it. The magnet field is strengthened. (I was in A+, too ;) ) - Dawn Ayers
What is the relationship between electron and magnetism?
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.
A magnetic field around a current carrying wire forms?
concentric circles around the wire
