3 - 2 , 1 km wires ( so acting like infinite wires ) , both have same current , no direction specified , , separated by 1 meter distance and having between them a magnetic force of module 0.02 N .
find the current i=
the definition of 1 ampere has same conditions except the force between should be 2*10^-7 ,
The Attempt at a Solution
0.02 N is 2 *10^-2 so this is 100000 times bigger than 1 amp ?
or other way around , 1/100000 amps ?
im positive this can be solve using symetry and the ampere definition ,
