A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,:ch1 and magnetic materials.

The Tabletop Explainer is an intermittent educational vlog presenting answers to viewer questions, brief science lessons, and ideas for teachers and...

Learn what magnetic fields are and how to calculate them. What are magnetic fields? This is the currently selected item.

Both the electric field and magnetic field can be defined from the Lorentz force law The magnetic quantity B which is being called "magnetic field" here is sometimes called "magnetic flux density".

A magnetic field is an invisible field that exerts a magnetic force on substances that are sensitive to Larger examples include the Earth's magnetic field, and those that are created by other celestial...

A magnetic field is an invisible physical phenomenon caused ("induced") by an electric current. The current may be as small as an orbiting electron in an atom or as large as that in household wiring or the electric currents flowing in Earth's core.

The attraction known as magnetism occurs when a magnetic field is present, which is a field of force produced by a magnetic object or particle. It can also be produced by a changing electric field and is...

There are different types of magnets. Bar magnets, rod magnets, horseshoe magnet, ring magnet Magnetic field lines are imaginary lines around the magnet. The magnitude of a field is indicated by...

In physics , a magnetic field is an entity produced by moving electric charges ( electric currents ) that exerts a force on other moving charges. (The quantum mechanics|quantum-mechanical spin of a particle produces magnetic fields and is acted on by them as though it were a current...

If two bar magnets are brought close together, the like poles will repel each other, and the unlike poles attract each other. If a charge moves through a magnetic field at an angle, it will experience a force.

The magnetic field is a field, produced by electric charges in motion. It is a field of force causing a force on The earth also has its natural magnetism which protects it from solar waves from the sun.

A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. Magnetic fields have had many uses in ancient and modern society.

Magnetic Fields. We have thus seen that forces can be applied between magnets and between magnets and ferromagnetic materials without any contact between the objects. This is reminiscent of...

Electromagnetism and magnetism. Magnets have a north pole and a south pole. A magnet creates a magnetic field around it. You cannot see a magnetic field, but you can observe its effects.

Magnetic Fields. Magnetism is closely related to electricity. In essence, magnetism is a force Magnets are polarized, meaning every magnet has two opposite ends. The end of a magnet that...

Magnets and Magnetic Fields: A brief introduction to magnetism for introductory physics students. The magnetic field of a long straight wire has more implications than one might first suspect.

Both magnetic fields and magnetic forces are more complicated than electric fields and electric The magnetic field does not point along the direction of the source of the field; instead, it points in a...

A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron.

Magnets & Magnetic Fields. Magnets are used all over the world in almost all modern devices from computer hard drives to the latest environmentally friendly cars and transportation.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges Since both strength and direction of a magnetic field may vary with location, they are described as a...

The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields.

Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field A magnetic field extends infinitely, though it weakens with distance from its source.

Magnetic fields are different from electric fields. Although both types of fields are interconnected If you place an object in a magnetic field, it will be affected, and the effect will happen along field lines.

A magnetic field is generated due to: Magnetic moment. Moving charge. Magnets have two poles, a north and a south. Like poles repel, unlike poles attract. Magnets will try to align their poles. North and south pole: pole of earth is reversed; geographic north is magnetic south and vice versa.

Magnetic field definition is - the portion of space near a magnetic body or a current-carrying body in Recent Examples on the Web The magnetic field can easily destabilize and bring down the rest of...

A magnetic field exerts a force on particles in the field due to the Lorentz force, according to Georgia State University's HyperPhysics website. The motion of electrically charged particles gives rise to...

Magnetic field lines are a visual representation of the invisible lines of force in a magnetic field. By convention, the lines trace the force from the north to south pole of a magnet.

Earth's magnetic field is changing in other ways, too: Compass needles in Africa, for instance, are drifting about 1 degree per decade. And globally the magnetic field has weakened 10% since the...
