Problem 7
Q

A 16-cm-diameter circular loop of wire is placed in a 0.50-T magnetic field.

  1. When the plane of the loop is perpendicular to the field lines, what is the magnetic flux through the loop?
  2. The plane of the loop is rotated until it makes a 4242 ^\circ angle with the field lines. What is the angle θ\theta in Eq. 21–1 for this situation?
  3. What is the magnetic flux through the loop at this angle?
A
  1. 1.0×102 Wb1.0 \times 10^{-2} \textrm{ Wb}
  2. 4848^\circ
  3. 6.7×103 Wb6.7 \times 10^{-3} \textrm{ Wb}
