If the current in a circular loop is doubled, how does the magnetic field at the center change?
Step 1: Understand that a circular loop of wire creates a magnetic field when an electric current flows through it.
Step 2: Know that the strength of the magnetic field at the center of the loop depends on the amount of current flowing through the loop.
Step 3: Remember that if you double the current, the magnetic field strength also changes.
Step 4: Since the magnetic field is directly proportional to the current, doubling the current means the magnetic field at the center will also double.
