Two current loops are coaxial and coplanar. One has radius a and the other has radius 2a. Current 2I in the outer loop is anti-parallel to current I in the inner loop. The magnitude of the magnetic field at the centre of the two loops is a. (mu_0 * I) / a b. (2 * mu_0 * I) / a c. 0 d. (mu_0 * I) / (4a) e. (mu_0 * I) / (2a) The correct answer is: 0

Step 1
We have two current loops, one with radius a and current I, and the other with radius 2a and current 2I. The currents are anti-parallel, meaning they flow in opposite directions. Show more…

co In Fig. $29-46$, two concentric circular loops of wire carrying current in the same direction lie in the same plane. Loop 1 has radius $1.50 \mathrm{~cm}$ and carries $4.00 \mathrm{~mA}$. Loop 2 Figure 29-46 Problem 16. has radius $2.50 \mathrm{~cm}$ and carries $6.00$ $\mathrm{mA}$. Loop 2 is to be rotated about a diameter while the net magnetic field $\vec{B}$ set up by the two loops at their common center is measured. Through what angle must loop 2 be rotated so that the magnitude of that net field is $100 \mathrm{nT}$ ?
Four long straight wires, each with current $I$ overlap to form a square with side $2 r$ (a) Find the magnetic field at the center of the square. (b) Compare your answer with the magnetic field at the center of a circular loop of radius $r$ carrying current $I \text { [see } \mathrm{Eq} .(19-16)]$ (FIGURE CANNOT COPY)
