What 4 materials are magnetic fields

The thermal motion remember the higher the temperature, the faster the atoms move of atoms eventually may cause most of the atoms to return to random orientation.

Magnetic Field Basics

My Bitesize. It all has to do with moving charges. A wire coils like the one shown in the picture below, can also produce magnetic field similar to that of a magnet.

The fields affect neighboring objects along things called magnetic field lines. We will see later that, the motion of electrons moving electric charge is the fundamental reason of magnetism.

In this situation they act as a magnet - but only whilst in the magnetic field.

The Magnet and the Magnetic Field

Current Page: Substances that can only be temporarily magnetised are described as magnetically soft. Each domain may consist of billions of aligned atoms. Go for site help or a list of physics topics at the site map!

We can explain this dual nature of magnetic force by proposing that each magnet has two poles, north pole N and south pole S. Magnetic Field, The term magnetism comes from the region of Magnesia, a city in Western Turkey, where Greeks found lodestones, which attracted iron pieces across the space. Those poles are places where our planets field lines come together. Magnetic poles are the points where the magnetic field lines begin and end.

Change language English. Number of Visitors: When you remove the magnet, the nail becomes permanent magnet for a while. You can increase the strength of that magnetic field by increasing the current through the wire. We say that the mere presence of Earth sets up gravitational field in the surrounding space, and that we can represent this gravitational force effect with lines starting from Earth and radially diverging away to infinity.

Similarly, a magnet sets up a magnetic field in its surrounding space in which it magnetically affects any other magnetic material. Nervous System Geography4Kids: Links How Magnets Work - Introduction to Magnets and Magnetic Fields Magnet University - A variety of information from the fundamental theory of magnetism to advanced applications of magnetic materials Background Information for Magnets- Canada Science and Technology Museum - Some commonly asked questions about magnets and magnetism.

Useful Reference Materials Encyclopedia. It consists of a thin piece of a Magnet in needle shape, which is balanced on a nearly frictionless pivot point.

Although both types of fields are interconnected, they do different things. Please browse, research options, and choose the appropriate materials for your needs.
