Hi please help me with the Advance Physicis with the clear steps ! Ex21
Let a rectilinear wire suppose infinite and a rectangular
frame. The two conductors are coplanar. Calculate the flux
of the magnetic field through the rectangle produced by
the current I circulating in the wire. Look particularly at
the cases where d->0 and (1)/(2)**In(1+(b)/(d))**u0**I**a0<.
Answer:( 1)/(2)**In(1+(b)/(d))**u0**I**a
Ex21 Let a rectilinear wire suppose infinite and a rectangular

Answer: 1/2 * In (1+b/d) * u0 * I* a
