Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
How do electric currents produce magnetic fields?
Electric currents produce magnetic fields through the interaction of moving electric charges. When an electric current flows through a conductor, such as a wire, the moving electrons create a magnetic field around the conductor. This magnetic field is generated by the alignment of the electrons' spins and their movement in a particular direction. The strength of the magnetic field is directly proportional to the amount of current flowing through the conductor.
When does a copper wire produce a magnetic field?
A copper wire produces a magnetic field when an electric current flows through it. This is due to the interaction between the moving electrons in the wire and the magnetic field they generate.
How does a generator produce electric current?
A generator produces electric current by converting mechanical energy into electrical energy through the process of electromagnetic induction. This involves rotating a coil of wire within a magnetic field, which creates a flow of electrons and generates an electric current.
How can you produce current in a wire with a magnet that is stationary?
When a magnet is stationary near a wire, it can produce current in the wire through electromagnetic induction. This happens when the magnetic field from the magnet interacts with the electrons in the wire, causing them to move and create an electric current.

What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
How do electric generators produce a current?
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
When does a copper wire produce a magnetic field?
A copper wire produces a magnetic field when an electric current flows through it. This is due to the interaction between the moving electrons in the wire and the magnetic field they generate.
Can direct current produce magnetic flux?
Moving electrons always have a magnetic field around them
How does a generator produce electric current?
A generator produces electric current by converting mechanical energy into electrical energy through the process of electromagnetic induction. This involves rotating a coil of wire within a magnetic field, which creates a flow of electrons and generates an electric current.
What does a coil do?
Produce a magnetic field as electric current passes through it.
How can you produce current in a wire with a magnet that is stationary?
When a magnet is stationary near a wire, it can produce current in the wire through electromagnetic induction. This happens when the magnetic field from the magnet interacts with the electrons in the wire, causing them to move and create an electric current.
How does a changing magnetic field produce an electric field according to electromagnetic theory?
According to electromagnetic theory, a changing magnetic field induces an electric field. This phenomenon is known as electromagnetic induction, where the changing magnetic field creates a force that causes electrons to move, generating an electric current.
How electric current causes magnetic field around conductor?
When an electric current flows through a conductor, it creates a magnetic field around the conductor. This is due to the interaction between the moving charges (the electrons in the current) and the magnetic fields they produce. The magnetic field strength is directly proportional to the current flowing through the conductor.
What particle flows to produce electric current?
Electrons are the particles that flow to produce an electric current in a conductor like a wire. When a potential difference is applied across a conductor, electrons move from the negative terminal to the positive terminal, creating an electric current.
