32.1 The two poles of a magnet are magnetic dipoles, which cannot be isolated o Like poles repel whereas unlike ones attract Magnetic materials are attracted to magnets and are attracted to both dipoles of the magnet. Whereas all neutral objects are attracted to a neutral rod, only certain objects are attracted to magnets. The geographic north pole is the magnetic south pole 32.2 Figure 32.2.c shows that with the right-hand rule, we point our thumb in the direction of the current and curl our fingers naturally in the direction of the magnets’ north poles A magnetic field, composed of vectors, exists at all points around an electric current such that the force on the north pole is parallel to the magnetic field
