Magnetic field - Wikipedia


A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field.

Magnetic Field Lines


Magnetic Field Lines. Einstein is said to have been fascinated by a compass as a child, perhaps musing on how the needle felt a force without direct physical contact.

Magnetic field lines | Brilliant Math & Science Wiki


Nevertheless, they are useful tools for thinking about magnetic field lines and to otherwise conceptualize ideas about magnetism.

Magnets and Electromagnets


The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet.

Magnetic Fields | (i) Field lines


Steel is said to be magnetically ‘hard’. Magnetic field lines. We imagine a magnet to be surrounded by an invisible ‘magnetic field’, which we represent by field lines or lines of force.

The idea of magnetic field lines and magnetic fields was first examined by Michael Faraday and later by James Clerk Maxwell.

An alternative method of visualizing the magnetic field is to use "magnetic field lines."
