CircularWire¶

class plasmapy.formulary.CircularWire(normal, center: Unit(‘m’), radius: Unit(‘m’), current: Unit(‘A’), n=300)¶

Circular wire(coil) class

Parameters

normal – three-dimensional normal vector of the circular coil
center (astropy.units.Quantity) – three-dimensional position vector of the circular coil’s center
radius (astropy.units.Quantity) – radius of the circular coil
current (astropy.units.Quantity) – electric current

Methods Summary

`magnetic_field`(p)	Calculate magnetic field generated by this wire at position `p`
`to_GeneralWire`()	Convert this `Wire` into a `GeneralWire`.

Methods Documentation

magnetic_field(p)¶

Calculate magnetic field generated by this wire at position p

Parameters: p (astropy.units.Quantity) – three-dimensional position vector
Returns: B – magnetic field at the specified positon
Return type: astropy.units.Quantity

Notes

We use n points Gauss-Legendre quadrature to compute the integral. The default n is 300.
