Question

The direction of the magnetic dipole moment of a current loop is determined by the:

Options

• Right-Hand Thumb Rule

• Fleming's Right-Hand Rule for induced current

• Left-Hand Thumb Rule

• Lenz's Law

Answer 1

The magnetic moment is a vector quantity whose direction is determined by the Right-Hand Thumb Rule: curl the fingers of the right hand in the direction of conventional current, and the extended thumb points along the magnetic moment.
