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.
Magnetic materials like neodymium are known for their strong magnetic fields due to a high degree of atomic alignment, making them ideal for applications where powerful magnets are required, such as in medical imaging machines or high-performance motors.
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. There are two types of magnetic poles, called the north magnetic pole and south magnetic pole.
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.
The Daily Galaxy on MSN: For the first time, scientists mapped magnetic fields on the far side of the sun without seeing it
Scientists have found a way to identify magnetic fields on the far side of the sun, a region that cannot be seen from Earth. By studying sound waves moving through the star, they can now detect not ...
