A closed loop of wire where charges continuously flow is called an electrical circuit. In this circuit, an electric current travels through the wire due to a voltage source, such as a battery, which provides the necessary energy to move the charges. This continuous flow allows electrical devices to operate, as they convert electrical energy into other forms of energy, such as light or motion. The circuit must be complete and unbroken for the current to flow effectively.
What else can I help you with?
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
If your car moves over a wide closed loop of wire embedded in a road urface is the magnetic field on the earth within the loop?
yes the perpendicular component of earths magnetic field passes through the loop even if the car is moving above it or not , but no current is induced in the loop since it is not moving
What are the essential parts of a transformer?
A magnetic core made of iron laminations, forming a closed loop, and two or more coils of copper wire wound to intersect the core.

How do you sterilize a wire loop?
To sterilize a wire loop, first, hold the loop with forceps and place it in a flame, such as that of a Bunsen burner, until it glows red-hot. This process incinerates any microorganisms present on the loop. Allow the loop to cool before using it to avoid killing the desired cultures or samples. Always ensure the loop is handled using sterile techniques to maintain its sterility.
When a loop of current carrying wire turns continuously in a magnetic field?
emf will be induced
What is produced when a magnetic field moves relative to a closed wire loop?
Faraday says you will induce a current in the wire.
When there is a change in the magnetic field in a closed loop of wire?
An electromotive force (EMF) is induced in the wire loop due to Faraday's law of electromagnetic induction. This causes a current to flow in the wire loop, creating an electrical circuit. The induced current generates its own magnetic field that opposes the original change in magnetic field.
What condition necessary for the sustained flow of charge in wire?
The necessary condition for the sustained flow of charge in a wire is the presence of a closed circuit or path for the current to flow in. This closed path allows the charges to continuously move and circulate through the wire. Additionally, an external source of electromotive force, such as a battery or a power supply, is required to provide the energy needed to maintain the flow of charge.
How does Amperes law relate to the calculation of the magnetic field around a current-carrying wire?
Ampere's law states that the magnetic field around a closed loop is directly proportional to the current passing through the loop. This law is used to calculate the magnetic field strength around a current-carrying wire by integrating the magnetic field along a closed loop surrounding the wire.
What is binary cord?
Wire carrying negative and positive charges in a closed circuit. It doesnt have earth.
What is a circuit that only has one loop of wire?
A simple circuit that has only one loop of wire is a series circuit. In a series circuit, the components are connected in a single path, forming a closed loop for the current to flow through. If one component fails, the entire circuit will be broken.
What does a closing look like?
A closed circuit would look like a circuit which has no disconnected wire and when the current is flowing continuously
What happens when there is a change in the magnetic field in a closed loop of wire?
When there is a change in the magnetic field in a closed loop of wire, an electromotive force (EMF) is induced in the wire, generating an electric current. This phenomenon is known as electromagnetic induction, described by Faraday's law of electromagnetic induction. The induced current creates a magnetic field that opposes the change in the original magnetic field.
What are the steps that describe the movement of electric charges in a closed circuit?
Charges leave the dry cell. Charges move through the switch. Charges move from the switch to the light. Charges move through the light bulb. Charges move through the wire leading back to the dry cell.
What does a close circuit looks like?
A closed circuit would look like a circuit which has no disconnected wire and when the current is flowing continuously
What is the shape of the loop of wire in the scenario where a loop of wire is in the shape of two concentric semicircles as shown?
The shape of the loop of wire is two concentric semicircles.
