Earth's magnetic field - Wikipedia

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it meets the solar wind, a stream of charged particles emanating from the Sun.Its magnitude at the Earth's surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss). Approximately, it is the field of a magnetic dipole currently tilted at an angle ...

Magnetic field - Wikipedia

A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials. In everyday life, the effects of magnetic fields are often seen in permanent magnets, which pull on magnetic materials (such as iron) and attract or repel other magnets.Magnetic fields surround and are created by magnetized material and by moving electric charges (electric ...

magnetic field | Definition & Facts | Britannica.com

Magnetic field: Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field.

Magnets and Electromagnets - HyperPhysics Concepts

The magnetic field lines of a bar magnet can be traced out with the use of a compass. The needle of a compass is itself a permanent magnet and the north indicator of the compass is a magnetic north pole.

GCSE PHYSICS - Electromagnetism - Coil - Magnetic Field ...

Electromagnetism. Electromagnetic Coil.. The magnetic field around a straight wire is not very strong. A strong field can be made by coiling the wire around a piece of soft iron. This electromagnet is sometimes called a solenoid. The shape of the magnetic field is the same as a bar magnet.. The soft iron inside the coil makes the magnetic field stronger because it becomes a magnet itself when ...

SEEING MAGNETIC FIELD PATTERNS IN 3D A simple science project 1988 William Beaty, Museum of Science, Boston . Iron filings align themselves in strong magnetic fields. This reveals the shape of the field …

What creates Earth's magnetic field? | Cosmos

Instead, Earth’s magnetic field is caused by a dynamo effect. The effect works in the same way as a dynamo light on a bicycle. Magnets in the dynamo start spinning when the bicycle is pedalled ...

Geography4Kids.com: Earth Structure: Magnetic Field

Fields Of Magnetic Forces We glossed over the idea that the outer core of the Earth creates the magnetic field and the magnetosphere for the planet. How does it do it? The molten iron …

Physics4Kids.com: Electricity & Magnetism: Magnetic Fields

Magnetic Field Basics Magnetic fields are different from electric fields. Although both types of fields are interconnected, they do different things. The idea of magnetic field lines and magnetic fields was first examined by Michael Faraday and later by James Clerk Maxwell.Both of these English scientists made great discoveries in the field of electromagnetism.

Electricity & Magnetism - Magnetic Field Cube

The Magnetic Field Viewing Cube is a striking new way for students to observe magnetic field lines - in 3D! Even students who have seen magnetic fields demonstrated on a two-dimensional plane will be fascinated. Save yourself the mess of loose iron filings with this sealed, transparent acrylic box...
