North poles point north, south poles point south. Like poles repel, unlike poles attract. Magnetic forces attract only magnetic materials.
Magnetic forces act at a distance.
While magnetized, temporary magnets act like permanent magnets. A coil of wire with an electric current flowing through it becomes a magnet. Putting iron inside a current-carrying coil increases the strength of the electromagnet. A changing magnetic field induces an electric current in a conductor. A charged particle experiences no magnetic force when moving parallel to a magnetic field, but when it is moving perpendicular to the field it experiences a force perpendicular to both the field and the direction of motion.
