What else can I help you with?
What happens when white light passes through a strong magnetic field?
I have the impression that light is not affected by magnetic fields - at least in a vacuum. If traveling through other substances, the magnetic field can change the light's polarization.
Any magnetic properties properties occur when?
When materials are placed in a magnetic field, they can exhibit various magnetic properties such as attraction or repulsion, alignment of magnetic dipoles, and induction of a magnetic field in the material itself. These properties depend on the type of material and its composition, as well as the strength and direction of the magnetic field applied to it.
What makes an object magnetic?
An object becomes magnetic when its atoms have aligned magnetic moments, creating a magnetic field. This alignment can occur naturally in certain materials like iron, nickel, and cobalt, or can be induced through exposure to a magnetic field.
What energy transformations occur in a electromagnet?
Electrical energy is converted into magnetic energy in an electromagnet. When current flows through the coil of wire in the electromagnet, a magnetic field is created. This magnetic field can then exert a force on nearby magnetic materials.
What do you use in a vacuum to bend electronic beams?
Either an electrostatic field or a magnetic field. Each type is used in cathode ray tubes: generally, electrostatic in oscilloscopes, magnetic in television and computer CRTs.
Where in the Earth do magnetic fields occur?
Magnetic field lines are not a real observable thing, they are a tool used in physics to picture magnetic fields. A magnetic field is a continuous entity; it has no discrete force lines.
When magnetic flux through surface is zero?
When the magnetic flux through a closed surface is zero, it means that the magnetic field lines entering the surface equal the field lines leaving it. This can occur when the surface encloses no magnetic sources or when it lies parallel to the magnetic field lines. Mathematically, it can be expressed as ∮B⋅dA = 0, where B is the magnetic field and dA is the differential area vector.
Why Auroras do not happened near equator?
The auroras that are experienced near the polar regions occur because of the strength of the earth's magnetic field. The magnetic field is not very strong at the equator.
What is the related to the vibrations of an electrical charge or magnetic field that produces electromagnetic waves that can travel trough a vacuum such as space?
Electromagnetic waves are related to the vibrations of an electrical charge or magnetic field. These waves consist of synchronized oscillations of electric and magnetic fields that propagate through space at the speed of light. This allows them to travel through a vacuum like space.
How do metals exhibit magnetism?
Metals exhibit magnetism when the electrons in their atoms align in the same direction, creating a magnetic field. This alignment can occur naturally or be induced by an external magnetic field.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Why does moving electrons In a wire or coil create magnetic field especially that circular one around a single wire And is there magnetic field if we could shoot electrons as beam like in CRT?
Anytime any electrical charge moves a magnetic field is created. It does not matter if the moving charge is in a wire or in a vacuum. It does not matter if it is a single wire or a coil of wire. As soon as a charge moves a magnetic field is created.
