If the current in a circular loop is doubled, how does the magnetic field at the center of the loop change?
It remains the same
It doubles
It quadruples
It halves
The magnetic field at the center of a circular loop is directly proportional to the current; thus, if the current is doubled, the magnetic field also doubles.

Q: If the current in a circular loop is doubled, how does the magnetic field at the center of the loop change?
Solution: The magnetic field at the center of a circular loop is directly proportional to the current; thus, if the current is doubled, the magnetic field also doubles.
Steps: 5
Step 1: Understand that a circular loop of wire carries an electric current.
Step 2: Know that the magnetic field created by the loop is related to the amount of current flowing through it.
Step 3: Remember that if the current increases, the magnetic field strength also increases.
Step 4: If the current is doubled, it means there is now twice as much current flowing through the loop.
Step 5: Since the magnetic field is directly proportional to the current, doubling the current will also double the magnetic field strength at the center of the loop.
