The force created on a straight stationary wire, carrying elecric current, placed in a magnetic field

The gyroradius (also known as radius of gyration, Larmor radius or cyclotron radius) is the radius of the circular motion of a charged particle in the ... more

where R is the electrical resistance of that material. Hopkinson’s law is a counterpart to Ohm’s law used in magnetic circuits. In electronic ... more

Energy density is the amount of energy stored in a given system or region of space per unit volume or mass, though the latter is more accurately termed ... more

A physical dipole consists of two equal and opposite point charges. When placed in an magnetic field, equal but opposite forces arise on each side of the ... more

In plasma physics, an Alfvén wave, named after Hannes Alfvén, is a type of magnetohydrodynamic wave in which ions oscillate in response to a restoring ... more

The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more

Magnetic reluctance, or magnetic resistance, is analogous to resistance in an electrical circuit (although it does not dissipate magnetic energy). In ... more

Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.

In magnetostatics, the force of attraction or repulsion between two current-carrying wires is often called Ampère’s force law. The ... more
