Question

Example 4: A long. straight wire carries a current of /; = 8.0 A. As Figure 21.30q illustrates, a circular loop of wire lies immediately to the right of the straight wire. The loop has a radius of R = 0.030 m and carries a current of b = 2.0 A. Assuming that the thickness of each wire is negligible. find the magnitde and direction of the net magnetic field at the center C of the loop. Figure 21.30 (a) A long, straight wire carrying a current /, lies next to a circular loop that carries a current /,. (b) The magnetic fields at the center C of the loop produced by the straight wire (B,) and the loop (B,).

Example 4: A long, straight wire caries a current of I1 = 8.0 A. As Figure 21.30a illustrates, a circular loop of
wire lies immediately to the right of the straight wire. The loop has a radius of R= 0.030 m and carries a current
of h = 2.0 A. Assuming that the thickness of each wire is negligible, find the magnitude and direction of the net
magnetic field at the center C of the loop.
Figure 21.30 (a) A long, straight wire
carrying a current I, lies next to a circular loop
that carries a current I2. (b) The magnetic
fields at the center C of the loop produced
by the straight wire (B,) and the loop (B2).
