Magnetic Effect Of Current
Question
Figure below shows two infinitely long and thin current carrying conductors X and Y kept in vacuum, parallel to each other, at a distance ‘a’.
(i) How much force per unit length acts on the conductor Y due to the current flowing througn X? Write your answer in terms of 
. 
(ii) Define ampere, in terms of froce between two current carrying conductors.
Solution
i) Force applied per unit length is given by,
ii) One ampere is the current which when flowing in each of two infinitely long parallel conductors 1 m apart in vaccum produces between them a force of exactly 2 x 10-10 Newton per metre of length.
