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.
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.
Nanowerk: Crystal defects follow the same math as electric currents and magnetic fields
Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing electric currents and magnetic fields. (Nanowerk News) A fundamental goal of ...
Crystal defects follow the same math as electric currents and magnetic fields
Protein crystallisation, a cornerstone technique in structural biology, is increasingly being refined through the controlled application of external electric and magnetic fields. By precisely ...
EurekAlert!: An electric discovery: Pigeons detect magnetic fields through their inner ear
This video explains what magnets are and how magnetic fields are generated through the alignment of atomic structures. Magnets influence electric currents, force interactions, and are used in many ...

Revolutionizing battery safety: magnetic fields unlock foolproof ID for electric vehicles' power packs
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.
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.
