ABCD is a rectangular loop made of uniform wire. If \(A D=B C=2 \mathrm{~cm}\), what is the magnetic force per unit length acting on wire $D C$ due to wire $A B$ if ammeter reads $20 \mathrm{~A}$. (The length of $A B$ and $D C$ are large in comparison with other two sides)
153753 The horizontal component of the earth's magnetic field at a certain place is $3.0 \times 10^{-5} \mathrm{~T}$ and the direction of the field is from the geographic south to the geographic north. A very long straight conductor is carrying a steady current of $2 \mathrm{~A}$. What is the force per unit length on it when it is placed on a horizontal table and the direction of the current is east to west?
