Question

Answer number 2 only and show solutions.

2. A long-straight wire carries a current of 0 A and 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 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. (Note that the magnetic field at point C is the sum of the electric field produced by a long-straight wire and a circular loop of wire)

Multiple Choices: Choose the BEST answer for each item.
1. Suppose there are a very long-straight wire and a rectangular coil, each carrying a current.
The wire and the coil lie in the same plane with the wire parallel to the long sides of the
rectangle. The coil is
a. attracted to the wire
b. repelled from the wire
c. neither attracted to nor repelled from the wire
d. no attraction or repulsion
2. A long-straight wire carries a current of 1₁ -8.0 A and 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
1₂ =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. (Note that the magnetic field at
point C is the sum of the electric field produced by a long-straight wire and a circular loop of
wire)
a. 1.7x10 T
b. 1.1x10 T
C. 2.3x10-³T
d. 3.8x10-²T
3. If the earth's magnetism is assumed to originate from a large circular loop of current within
the earth, then the plane of the current loop must be oriented
to the earth's
magnetic axis, and the direction of the current around the loop (when looking down on the
loop from the north magnetic pole) is
a. parallel, clockwise
b. parallel, counterclockwise
c. perpendicular, clockwise
d. perpendicular, counterclockwise
