In my note,(adsbygoogle = window.adsbygoogle || []).push({});

we have written the field strength tensor as:

[itex]F^{\mu\nu} =\partial ^\mu A^\nu -\partial ^\nu A^\mu =

\begin{pmatrix}

0&E_x &E_y&E_z \\

-E_x&0 &B_z &-B_y \\

-E_y&-B_z &0 &B_x \\

-E_z&B_y &-B_x&0

\end{pmatrix}

[/itex]

But if I look into another book or wiki it is written as:

[itex]

F^{\mu\nu} =\partial ^\mu A^\nu -\partial ^\nu A^\mu =

\begin{pmatrix}

0&-E_x &-E_y&-E_z \\

E_x&0 &-B_z &B_y \\

E_y&B_z &0 &-B_x \\

E_z&-B_y &B_x&0

\end{pmatrix}

[/itex]

Why is it possible to write the field strength tensor in both notations?

And are both notations really equal?
