Two nearby current loops are oriented as shown in FIGURE
24.49. Loop 1 is fixed in place; loop 2 is free to rotate.
Will it do so?
Homework Answers
The current in loop 1 generates a magnetic field.As figure shows,the field of loop 1 is upward as it passes loop 2.Because the field is perpendicular to the magnetic moment of loop 2,the field exerts a torque on loop 2 and causes loop 2 to rotate until its magnetic moment lines up with the field from loop 1.These two loops align so that their magnetic moments point in opposite directions.when aligned this way,the north pole of loop 1 is closest to the south pole of loop 2.This makes sense because these opposite poles attract each other.

Two identical small current carrying loops of wire are oriented along a common axis with the plane of their loops parallel to each other. See Figure EC. The distance between the loops, x, is much larger than the radius of each loop, R. The magnetic dipole moment of each loop is directed parallel to the axis, and the magnetic field that one loop creates at the center of the other loop is also parallel to the axis. So mu^rightarrow and...

An decreasing current I flows in an elliptical loop of wire. Two
loops of wire are placed as shown. Why is the flow of induced
current counterclockwise for loop 1? I thought that mutually
induced emf equals (-)M(di/dt). Doesn't the negative sign mean that
the mutually induced emf (and hence the induced current) will be in
the opposite direction of the rate of change of current? So why
wouldn't the induced current for loop 1 be clockwise?

Two circular current-carrying loops of wire are shown in the drawing. The inner loop has a radius of R0 and carries a current I0, while the outer loop has a radius of 2R0 and carries a current of 4I0. The currents are in opposite directions. If R0 = 0.20 m and I0 = 2.3 A, determine the magnitude and direction of the net magnetic field at the center of the two loops.

Consider two loops of currents. The first is fixed on an horizontal plane and its axis points up (i.e. it rotates counterclockwise if seen from above). The second loop has its center fixed on the same plane, but is free to rotate. What will be the final equilibrium position of the second loop once let go?
