Line of force - Wikipedia

A line of force in Faraday's extended sense is synonymous with Maxwell's line of induction. According to J.J. Thomson, Faraday usually discusses lines of force as chains of polarized particles in a dielectric, yet sometimes Faraday discusses them as having an existence all their own as in stretching across a vacuum. In addition to lines of force, J.J. Thomson—similar to Maxwell—also calls ...

Magnetic Field Lines - Florida State University

The iron filings line up along the magnetic field lines of the magnet. Note the circular pattern of the field lines. By convention, we say that the field lines emanate from the north pole of the magnet and re-enter the magnet through the south pole. Note also that the field lines are closer together at the poles than at the center of the magnet.

The plumb line will deflect a bit Southward in the Northern hemisphere. The angle of deflection depends on latitude. For a latitude of 47.3° N (Calumet, Michigan), and a plumb line 4,200 feet long, the angle is 0.003 radian, so the bob is nearly 5 meters South of the radial line passing through its support point.

Magnetic confinement fusion devices exploit the fact that charged particles in a magnetic field experience a Lorentz force and follow helical paths along the field lines. The simplest magnetic confinement system is a solenoid. A plasma in a solenoid will spiral about the lines of field running down its center, preventing motion towards the sides.

The Science of Magnetic Field Lines - ThoughtCo

A magnetic field is a vector, which means it has magnitude and direction.If electric current flows in a straight line, the right hand rule shows the direction invisible magnetic field lines flow around a wire. If you imagine gripping the wire with your right hand with your thumb pointing in the direction of the current, the magnetic field travels in the direction of the fingers around the wire.

Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet. The properties of magnetic lines of force are as follows. Magnetic field lines emerge from the north pole and merge at the south pole. As the distance between the poles increases, the density of magnetic lines decreases.

Hidden Portals in Earth's Magnetic Field | NASA

Portals form via the process of magnetic reconnection. Mingling lines of magnetic force from the sun and Earth criss-cross and join to create the openings. "X-points" are where the criss-cross takes place. The sudden joining of magnetic fields can propel jets of charged particles from the X-point, creating an "electron diffusion region."

Land mine - Wikipedia

A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used.
