Questions & Step-by-Step Solutions

What is the magnetic field at the center of a circular loop carrying current? (2022)
  • Step 1: Understand that a circular loop can carry an electric current, which creates a magnetic field around it.
  • Step 2: Know that the strength of the magnetic field at the center of the loop depends on two main factors: the amount of current flowing through the loop and the size of the loop (its radius).
  • Step 3: Remember that if the current increases, the magnetic field strength also increases. This means they are directly proportional.
  • Step 4: Also remember that if the radius of the loop increases, the magnetic field strength decreases. This means they are inversely proportional.
  • Step 5: Combine these ideas to conclude that the magnetic field at the center of the loop is stronger with more current and weaker with a larger radius.
