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) -> Unit("T")¶

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.
