A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent ...
A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. [1] The strength of the magnetic field generated is proportional to the amount of current through the winding. [1] An electromagnet is a type of magnet in which the magnetic field is produced by an electric current ...
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic ...
A school voucher, also called an education voucher in a voucher system, is a certificate of government funding for students at schools chosen by themselves or their parents. Funding is usually for a particular year, term, or semester. In some countries, states, or local jurisdictions, the voucher can be used to cover or reimburse home schooling expenses. In some countries, vouchers only exist ...
First primary school in Nigeria, built in 1845 [1] A high school building in Argos, Greece A school is the educational institution (and, in the case of in-person learning, the building) designed to provide learning environments for the teaching of students, usually under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. [2] In these ...
A military school teaches children of various ages (elementary school, middle school or high school) in a military environment which includes training in military aspects, such as drill. Many military schools are also boarding schools, and others are simply magnet schools in a larger school system. Many are privately run institutions, though some are public and are run either by a public ...
The magnetic field of permanent magnets can be quite complicated, especially near the magnet. The magnetic field of a small [note 6] straight magnet is proportional to the magnet's strength (called its magnetic dipole moment m). The equations are non-trivial and depend on the distance from the magnet and the orientation of the magnet.
