CircularWire

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

Bases: plasmapy.formulary.magnetostatics.Wire

Circular wire(coil) class.

Parameters

• normal – Three-dimensional normal vector of the circular coil.

• center (Quantity) – Three-dimensional position vector of the circular coil’s center.

• radius (Quantity) – Radius of the circular coil.

• current (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 (Quantity) – Three-dimensional position vector.

Returns

B – Magnetic field at the specified position.

Return type

Quantity

Notes

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

to_GeneralWire()
