Both magnetic materials and moving electric charges induce magnetic fields.
"A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom."
A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
An electron is a spinning particle that creates a magnetic field. The spinning motion of the electron generates a magnetic dipole moment, resulting in the creation of a magnetic field around the electron.
No, lead is not magnetic. Lead is a diamagnetic material, meaning it creates a weak magnetic field in opposition to an externally applied magnetic field.
The magnetic field for an electromagnet is created by the flow of electric current through a coil of wire, which generates a magnetic field around the coil.
A changing magnetic field creates an electric field according to Faraday's law of electromagnetic induction. This phenomenon forms the basis for technologies such as generators, transformers, and electric motors.
A moving electric charge creates a magnetic field around it. This magnetic field interacts with other nearby magnetic fields and forces, leading to various electromagnetic effects such as electromagnetic induction or magnetic attraction/repulsion.
Current flow in any conductor creates a magnetic field, winding just concentrates it.
Selenium is diamagnetic; it only creates a magnetic field in opposition to an external magnetic field.

Selenium is diamagnetic; it only creates a magnetic field in opposition to an external magnetic field.
The Earth's magnetic field is generated by the movement of molten iron and nickel in its outer core. This movement, known as convection, creates electric currents that produce the magnetic field.
No, lead is not magnetic. Lead is a diamagnetic material, meaning it creates a weak magnetic field in opposition to an externally applied magnetic field.

-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
A moving electric charge creates a magnetic field around it. This magnetic field interacts with other nearby magnetic fields and forces, leading to various electromagnetic effects such as electromagnetic induction or magnetic attraction/repulsion.
When an electric current flows through a conductor, it creates a magnetic field around the conductor. This phenomenon is described by the right-hand rule, where the direction of the magnetic field is determined by the direction of the current flow. The strength of the magnetic field is directly proportional to the amount of current flowing through the conductor.
Copper is not magnetic because its atomic structure does not allow its electrons to align in a way that creates a magnetic field.
