Hi, in this question we have a long straight wire i1 and the rectangular loop current carrying conductor which is i2.
00:07
So, we have the direction of i1 is same as i2 therefore the force f1 is attractive in nature whereas the direction of i2 in this line is opposite to that of i1.
00:18
So, this is repulsive in nature.
00:21
So, f2 is repulsive in nature.
00:24
So, the current carrying conductor has a induced magnetic field in it.
00:30
Now, we have the magnetic field b is given by it is mu naught i divided by 2 pi into r.
00:40
Now, we have the force per unit length is given by so force per unit length is mu naught into i1 into i2 divided by 2 pi into r where mu naught is the absolute permeability of the free space.
00:56
Now, we have force f1 which is attractive in nature is equal to it is mu naught into i1 into i2 into length l divided by 2 pi the separation is c.
01:09
So, this is c into so this is in negative x direction.
01:14
So, this is minus x which is the unit vector corresponding to negative x is minus i cap...
