FiniteStraightWire¶

class plasmapy.formulary.FiniteStraightWire(p1: Unit("m"), p2: Unit("m"), current: Unit("A"))¶

Bases: plasmapy.formulary.magnetostatics.Wire

Finite length straight wire class.

p1 to p2 direction is the possitive current direction.

Parameters:	p1 (`astropy.units.Quantity`) – three-dimensional Cartesian coordinate of one end of the straight wire p2 (`astropy.units.Quantity`) – three-dimensional Cartesian coordinate of another end of the straight wire 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

Let \(P_f\) be the foot of perpendicular, \(\theta_1\)theta_2`) be the angles between \(\overrightarrow{PP_1}\)overrightarrow{PP_2}`) and \(\overrightarrow{P_2P_1}\).

to_GeneralWire()¶: Convert this Wire into a GeneralWire.
