What: "Being a bit more quantum mechanical, these current loops are treated as 'magnetic dipoles'--a magnetic analog of electric dipoles. Electric dipoles are much easier to explain and visualize because with electricity we have point charges---an electric dipole is like a positive and a negative charge at either ends of a rod, like a barbell. Since magnetic dipoles aren't as easy, just keep this picture in mind in place--it's not physically correct, but it gets the job done."
