... It is easy to find that a symmetric tensor has 10 independent components, while an antisymmetric one has only six. If the field tensor were an antisymmetric one we would need only 3 new components. Remark, btw, that the LT transforms symmetric tensors into symmetric ones, and the same for antisymmet ...

... The same situation is true for a single coil of wire in which the current is changing. If a current is increasing, then there is an increase of magnetic flux produced. This produces a back EMF which opposes the change. This property is called self inductance, and similar to mutual inductance is give ...
