Alfvén Number

Wolfram Research

The Alfvén number describes the relative scale for phenomena within an Alfvén wave, a type of magnetohydrodynamic wave in which ions oscillate in response to a restoring force provided by an effective tension on the m...

Chandrasekhar Number

Wolfram Research

The Chandrasekhar number is a dimensionless quantity used in magnetic convection to represent the ratio of the Lorentz force to the viscosity.

Circular Current Loop

Wolfram Research

A circular current loop is a current constrained along a circular path by an infinitely thin wire.

First Cowling Number

Wolfram Research

The Cowling number expresses the magnetic-to-inertia forces ratio.

Hartmann Number

Wolfram Research

The Hartmann number, related to the Chandrasekhar number, is a dimensionless quantity used in magnetic convection to represent the ratio of the Lorentz force to the viscosity.

Helmholtz Coil Field at Center

Wolfram Research

A Helmholtz coil is a device for producing a region of nearly uniform magnetic field. It consists of two solenoid electromagnets on the same axis.

Helmholtz Coil Field at Arbitrary Distance

Wolfram Research

A Helmholtz coil is a device for producing a region of nearly uniform magnetic field. It consists of two solenoid electromagnets on the same axis.

Infinitely Long Wire Magnetic Field

Wolfram Research

A magnetic field is the magnetic effect of electric currents and magnetic materials for an infinitely long wire; it is created by the current flowing through the wire.

Lorentz Force Using Particle Speed

Wolfram Research

The Lorentz force is the combination of electric and magnetic force on a point charge due to electromagnetic fields.

Lorentz Force Using Current

Wolfram Research

The Lorentz force is the combination of electric and magnetic force on a point charge due to electromagnetic fields.

Second Cowling Number

Wolfram Research

The Cowling number expresses the magnetic-to-intertia forces ratio.

Transformer Universal EMF Using Flux Density

Wolfram Research

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromotive force, also called EMF, is the voltage developed by any source of el...
