Worksheet: Using the Biot–Savart Law to Calculate the Magnetic Field of a Constant Current

Q1:

There is a 10 amp current through a square loop for which each side is 20 cm in length. At each corner of the loop is a 0.010-cm segment that connects the longer wires as shown. Calculate the magnitude of the magnetic field at the center of the loop.

  • A 2 . 0 × 1 0 8 T
  • B 1 . 5 × 1 0 8 T
  • C 2 . 5 × 1 0 8 T
  • D 1 . 0 × 1 0 8 T
  • E 3 . 0 × 1 0 8 T
