A Random Test from Magnetism

Each question carries one mark What is a magnetic dipole? What is the difference between electric field lines and magnetic field lines? Write an expression for the magnetic field at a point on the axis of a circular group carrying current and hence write equation for the magnetic dipole moment of the loop? What is…… Continue reading A Random Test from Magnetism
