Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
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.
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
What happens to a current carrying wire in a magnetic field when it is reversed?
the wire would be deflected perpendicular to the magnetic field in the opposite direction.
What is the cause of a magnetic field about a current-carrying wire?
The cause is the current.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
What is produced around a wire that has a current?
Magnetic field.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
Passing a magnetic field by a wire creates a what?
Passing a wire near a magnetic field induces an electric current in the wire.
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.
What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.
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
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
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.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
