No. Because there is a potential difference
Yes, it is possible.
'Cryogenic' electromagnets, such as those in MRI machines, are supercooled
loops of superconducting material, with no ends, in which an electric current is
started by a temporary potential difference. But then the ends are joined, and
the current continues, in principle for as long as the loop remains supercooled.
I have seen an MRI loop current sustained for 4 months, and stopped only when
a lab assistant allowed a liquid helium cooling tank to run dry.

What is the difference between conventional current and electric current?
Conventional current is the flow of positive charge from higher potential to lower potential, while electric current is the flow of electrons from lower potential to higher potential.
Why does the current flow through wire?
Current flows through a wire when there is a difference in electric potential between two points. This potential difference creates an electric field that drives the flow of electric charge (current) through the wire.
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
Is The units of electric current is the volt?
NO! (the units of electric current is Amperes).
What Electric potential or potential difference?
Electric potential (also known as voltage) is the amount of electric potential energy per unit of charge at a specific point in an electric field. It is measured in volts (V) and determines the ability of a charge to do work. Potential difference is the difference in electric potential between two points in an electric field and is responsible for the flow of electric current between those points.
What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.
Is units of electric current a volt?
Electric current is measured in amps not voltsElectric voltage is measured in volts.
What is a electrical current is produced when charges are accelerated by an electrical field to move to a position of potential energy that is?
An electric current is produced when charges are accelerated by an electric field and move to a position of potential energy difference. This movement of charges generates a flow of electric charge that constitutes an electric current.
How does potential difference induce an electric current?
A potential difference, or voltage, creates an electric field along a conductor. This electric field exerts a force on the free electrons within the conductor, causing them to move in response to the voltage. This movement of electrons constitutes an electric current flowing through the conductor.
Why does connecting an electric device to a battery produces a current?
When an electric device is connected to a battery, an electric current is produced due to the difference in potential between the positive and negative terminals of the battery. This potential difference, also known as voltage, creates an electrical force that pushes the flow of electric charge (current) through the circuit and powers the device.
A what difference is the what that causes charges to move?
The difference in electric potential between two points is what causes charges to move. When there is a potential difference, charges will flow from the higher potential to the lower potential, generating an electric current. This movement of charges is essential for the functioning of electrical circuits.
What is the amount of potential energy per unit charge that a static charge or electric current has?
The amount of potential energy per unit charge that a static charge has is equivalent to the electric potential at that point. For electric current, the potential energy per unit charge can be calculated by multiplying the electric potential difference across the circuit by the amount of charge.
