'''Christopher Parker''' (born [[August 24]] [[1983]]) is a [[United Kingdom|British]] [[actor]]. He is most notable in the role of Spencer Moon in the [[BBC]] [[soap opera]] ''[[EastEnders]]''.

==Introduction==

He has also appeared in ''[[The Bill]]'' as an extra and as a [[stunt double]] in ''[[Harry Potter and the Chamber of Secrets (movie)|Harry Potter and the Chamber of Secrets]]'', and he made an appearance following his fame on ''EastEnders'' on ''[[Strictly Come Dancing]]'', in which he was a finalist.

'''[[Electron spin resonance|Electron Paramagnetic Resonance]]''' was invented after [[Second World War]] by [[Zawojski]]. Nowdays '''EPR''' is a major part of [[spectroscopy|radiospectroscopy]] and elementary investigations, and has many practical applications.

In [[November 2004]] Parker hit the headlines in the UK because it was revealed he had attempted [[suicide]] by slashing his [[wrist]]s. It had been alleged by a tabloid newspaper that he had paid a girl to falsely claim that she had slept with him, in an attempt to dispel alleged rumours that he might be gay. Parker was placed on extended leave by Eastenders, but his contract was terminated shortly afterwards.

Magnetic Field is discrabed by some constants and units:

{{UK-actor-stub}}

* [[Magnetic induction]] <math>\bar{B}</math> in [[tesla]]s [T]

* [[Magnetic flux dencity]] <math>\bar{H}</math> in [<math>\frac{A}{m}</math>]

* <math>\bar{B}</math> and <math>\bar{H}</math> relationship: <br>

<p align="center"><math>\bar{B}=\mu_0\bar{H}</math></p>

* CGS unit for [[magnetic induction]] is [[Gauss]] [G] which is equivalent of 10^-4 [T]

Furthermore in describing EPR, following units are very important:

* [[Planck]] constant <math>h=6,63\times 10^{-4}</math> [J.s]

* [[Boltzmann]] constant <math>k=1,38\times 10^{-23}</math>[J.K^-1]

* [[Bohr]] magnetone <math>\beta=9,27\times 10^{-24}</math>[J.T^-1]
