題目如下
Two identical, perfectly conducting loops are far apart
and share the same axis, Each has self-inductance L
and a current I flowing in the same direction, so the
energy in each loop is (1/2)LI^2 . They are then brought
together and superposed.
(a) What is the final current in each loop?
(b) What is the total energ of the final system?
