Which of the following could be the primary origins of magnetism?

Correct option is B

Correct answer is b
Explanation:
Electron movement: Electrons orbiting the nucleus create a tiny current, similar to how current flows in a wire. This current generates a magnetic field around the atom. 
Electron spin: Electrons also have an intrinsic spin, which can be thought of as a rotation around their own axis. This spin also contributes to the magnetic field generated by the electron. 
Atomic currents: The movement of electrons around the nucleus is termed as an atomic current.
Intrinsic spin: The inherent rotation of electrons around their own axis is called intrinsic spin.
Magnetic field generation: Both atomic currents and electron spin contribute to the creation of a magnetic field around an atom.
