How does a current carrying wire differs from a wire through which no current is flowing?
A current-carrying wire has moving electrical charges, creating a magnetic field around it, while a wire with no current has static charges at rest. The current-carrying wire produces a magnetic field perpendicular to the current flow, whereas in a wire with no current, there is no associated magnetic field. Additionally, a current-carrying wire generates heat due to the flow of electrons, while a wire with no current does not.

What does current carrying wire produce?
A current-carrying wire produces a magnetic field around it. This magnetic field strength is directly proportional to the amount of current flowing through the wire.
If you suspend a circular loop of wire carrying current by a thread how will you expect it to align itself?
The circular loop of wire carrying current will align itself in a plane perpendicular to the direction of the magnetic field created by the current flowing through the loop. This is a result of the magnetic force exerted on the current-carrying loop in the presence of the magnetic field.
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 are 3 ways to change characteristics of a magnetic field by an electric current?
By changing the magnitude of the current flowing through the conductor. By changing the direction of the current flow in the conductor. By changing the orientation or shape of the conductor carrying the current.
Why does a current carrying wire produce no magnetic field?
A current-carrying wire does produce a magnetic field around it according to Ampere's law, which states that a current generates a magnetic field. This phenomenon is the basis for the operation of electromagnets and the magnetic field produced is directly proportional the current flowing through the wire.

On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
Energy is a current carrying coil is stored in the form of?
The energy in a current-carrying coil is stored in the form of magnetic energy in the magnetic field produced by the coil. This magnetic energy is a result of the interaction between the current flowing through the coil and the magnetic field it generates.
What is the electrical resistance offered by a current carrying element that produces a drop of one volt when a current of one ampere is flowing through it?
Ohm's Law (V=IR) R=V/I=1
How may a coil carrying current increase magnetic flux density?
Increasing the current flowing through the coil will increase the magnetic field produced by the coil, which in turn will increase the magnetic flux density inside the coil. This relationship is described by Ampere's law which states that the magnetic field is directly proportional to the current flowing through the coil.
In a solenoid, will there be a magnetic field if there is no current flowing through it?
Yes, a solenoid will still have a magnetic field even if there is no current flowing through it.
What is most likely to be attracted to magnet a piece of glass a balloon a plastic piece chess or a coolpper wire carrying current?
A copper wire carrying current is most likely to be attracted to a magnet due to the magnetic field produced by the current flowing through it. Glass, a balloon, plastic piece, and chess piece are not typically attracted to magnets.
