I have uploaded the page from Jackson it is equation (6.119) I am trying to prove, however I must use Levi Cevita notation.

This is essentially a proof from Jackson. But I need to show it with levi Cevita notation.

The right is still a vector, I have Bolded the vector quantities B.

Hi Blue_leaf77, Yes that is correct! Thank you, I am sorry I typed it so poorly I am new to Physics forums.

Homework Statement I need to prove B.(Gradient . B) - B X(Gradient X B)=Del{i} [B{i}B{j} -1/2 (kroneker delta {ij} B^2] where I have used . as the dot product, {} as subscript. Thank you! Homework EquationsThe Attempt at a Solution [/B] I have attempted the solution but am not sure how it is...
