What else can I help you with?
A wire cannot cause a magnetic field if what?
A wire cannot cause a magnetic field if there is no current flowing through it. Magnetic fields are generated by the flow of electric current in a conductor.
What is the effect of the magnetic field of a short wire on nearby objects?
The magnetic field of a short wire can attract or repel nearby objects that are sensitive to magnetic forces. This effect is stronger the closer the objects are to the wire and can cause them to move or align in a certain direction.
How does the wire vibrate if the magnetic field is made vertical?
If the magnetic field is made vertical, it will exert a force perpendicular to the direction of current flow in the wire. This force will cause the wire to move up and down, vibrating vertically. The frequency of this vibration will be directly proportional to the strength of the magnetic field and the current flowing through 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.
Why does a current carrying wire deflect a magnetic compass?
A current-carrying wire generates a magnetic field around it due to the flow of electric charges. When the wire is placed near a magnetic compass, the magnetic field produced by the wire interacts with the magnetic field of the compass needle, causing the needle to deflect and align with the direction of the wire's magnetic field.

What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces 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 the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
Why does a current carrying wire deflect a magnetic compass?
A current-carrying wire generates a magnetic field around it due to the flow of electric charges. When the wire is placed near a magnetic compass, the magnetic field produced by the wire interacts with the magnetic field of the compass needle, causing the needle to deflect and align with the direction of the wire's magnetic field.
How is a current induced in a wire when a coil of wire moves through a magnetic field?
When a coil of wire moves through a magnetic field, the changing magnetic field induces a current in the wire through electromagnetic induction.
When you loop the wire with a current it will?
increase the strenght of the magnetic field. :)
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.
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.
