Hey, guys, I find a interesting phenomenon. When an external magnetic field is applied on a current loop, the net torque will try to align the loop's dipole moment with the magnetic field. And considering that electrical loops could be regarded as electromagnet, we change the current loop into a real magnet.However, at this time, the net external applied magnetic field try to align the magnet in the same line but the opposite direction with the applied field for opposite poles attract each other. Why do this happen? Is there any problem to exchange current loop with a real magnet??
