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

In this worksheet, we will practice using the Biot–Savart law to calculate the magnetic field produced by a current-carrying loop of wire.

Q1:

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

  • B9.4×10 T
  • C8.4×10 T
  • D9.0×10 T
  • E8.0×10 T
