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.
Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. Learn more about magnetism in this article.
The meaning of MAGNETIC is possessing an extraordinary power or ability to attract. How to use magnetic in a sentence.
Scientists have recently discovered materials with new magnetic properties. In a laboratory at the Massachusetts Institute of Technology, scientists manipulate quartz tubes containing crystals ...
Just as electric charges have electric fields surrounding them, magnets have magnetic fields that surround them. This page explores the important concept of the magnetic field and how magnetic field lines communicate its strength and direction.
Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents.
Earth’s magnetic field protects us from cosmic radiation and solar wind. It serves as a shield to the ozone layer and reduces the impact of ultraviolet radiation on our planet. This dynamic force, generated by the movement of liquid iron in Earth’s outer core, undergoes periodic changes and experiences magnetic north-south flips every few hundred thousand years. Earth’s magnetic field ...
You use magnetic to describe something that is caused by or relates to the force of magnetism. The electrically charged gas particles are affected by magnetic forces.
A psychologist reveals nine common things that the most magnetic people in a room actually do, and why. Plus, tips on how to become more magnetic.
Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time.
Magnetism is a fascinating force. Understanding the different types and strengths of magnetic fields guides numerous technologies around us.
Some animals, such as pigeons, bees, and salmon, can detect Earth's magnetic field and use it to navigate. Scientists aren't sure how they do this, but these creatures seem to have magnetic material in their bodies that acts like a compass.
Explore the interactions between a compass and bar magnet. Relate the Earth’s magnetic field to a bar magnet. Vary the magnet's strength, and see how things change both inside and outside. Measure the direction and magnitude of the magnetic field.

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.
MAGNETIC definition: 1. (of a metal object or material) able to attract objects or materials containing iron or steel….
- of or pertaining to a magnet or magnetism. 2. having the properties of a magnet. 3. capable of being magnetized or attracted by a magnet. 4. of, pertaining to, or being a medium created with magnetically sensitive material for storing electronic data, as a magnetic card or disk.
