Passing an electric current through a certain substance produces oxygen and sulfur This substance cannot be a?
This substance cannot be water, because passing an electric current through water, in a process called electrolysis, produces hydrogen and oxygen gas, not oxygen and sulfur.
How can we increase the magnitude of the magnetic field of an electric magnet?
You can increase the magnitude of the magnetic field of an electromagnet by increasing the number of turns in the coil, increasing the current flowing through the coil, and using a ferromagnetic core material within the coil. These factors collectively enhance the strength of the magnetic field generated by the electromagnet.
Why electrovalent compounds conduct electricity?
Electrovalent compounds, or ionic compounds, conduct electricity because they have ions that are free to move and carry an electric charge. When an electric field is applied, these charged particles can move and carry the electric current through the compound.
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electric current flowing through the coil is turned off or interrupted. This interrupts the magnetic field generated by the coil, causing it to demagnetize.
When an electric charge moves through a conductor there is an electric in the conductor?
When an electric charge moves through a conductor, an electric current is generated in the conductor. The flow of electrons creates a flow of current in the conductor, which is the movement of electric charge through the material.
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
What process by which an electric current is produced?
An electric current is produced through a process called electromotive force (EMF), which can be generated by batteries, generators, or solar cells. When a circuit is closed, the EMF causes the flow of electric charge, resulting in an electric current.
What is the controlled movement of electrons through a substance is called?
The controlled movement of electrons through a substance is called electric current. It is the flow of electric charge carriers, usually electrons or ions, through a medium. Electric current is typically generated by the flow of electrons through a conductor in response to an electric field.
How an electric current formed?
An electric current is formed when a flow of charged particles, usually electrons, moves through a conducting material such as a wire. This flow is generated by a voltage difference, which creates an electric field that pushes the charged particles through the conductor.
How is electric current generated?
Electric current is generated when electrons flow through a conductive material, such as a wire. This flow of electrons is typically facilitated by a power source, such as a battery or a generator, which creates a potential difference that drives the movement of electrons. The rate at which these electrons flow past a given point in the circuit is what we refer to as electric current.
What is the induced current in the inner loop?
The induced current in the inner loop is the flow of electric charge that is generated by a changing magnetic field passing through the loop.
What generate current?
Current is generated by the flow of electric charge in a circuit. This flow can be created by sources such as batteries, generators, solar panels, or power plants. The movement of electrons through a conductor produces an electric current.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
Simple definition of electronic signal?
The simple definition of an electronic signal is a mode of communication that is generated through electric means. This refers to an electric current that is passed in an electromagnetic field.
What is the process by which electric current is generated by a wire a magnetic field?
When a wire moves through a magnetic field, it experiences a force that pushes free electrons along the wire, creating an electric current. This phenomenon is known as electromagnetic induction and is the basic principle behind how electric generators work. The strength of the current generated depends on factors such as the rate of motion of the wire and the strength of the magnetic field.
What happens when electric current passes through a spring?
When electric current passes through a spring, the spring can become magnetized. The magnetic field generated by the current induces a magnetic field in the spring, causing it to act like a magnet. This magnetic property can be harnessed in various applications, such as in electromagnets or speakers.
