Magnetic Field in Circular Loops

What is the direction of the magnetic field at the center of a circular loop with current flowing clockwise?

• To the left

• Out of the page

• To the right

• Into the page

Which rule is used to determine the direction of the magnetic field in a circular loop?

• Ampere's rule

• Fleming's rule

• Right-hand rule

• Left-hand rule

How does the right-hand rule for circular loops differ from its application in other scenarios?

• It uses the left hand instead

• The fingers point in the opposite direction

• The thumb points in the opposite direction

• It is not applicable to circular loops

What happens to the magnetic field at the center of a loop if the current is increased?

• It increases

• It remains the same

• It decreases

• It reverses direction

How does increasing the radius of the loop affect the magnetic field at the center?

• It reverses the magnetic field direction

• It has no effect

• It decreases the magnetic field

• It increases the magnetic field
