What happens when two north poles meet? Which material is attracted by a magnet? Where does the field of a bar magnet look strongest? Which way do field lines point outside a magnet? The N end of a compass needle is brought near a magnet's south pole. What happens? What is an electromagnet? Which change does NOT make an electromagnet stronger? An electromagnet lifts 4 clips with 10 turns. About how many with 30 turns of the same wire and cells? What happens to an electromagnet's poles if the current is reversed? A bar magnet is cut in half. What do you get? What do like poles do? — They repel each other. What do unlike poles do? — They attract each other. Name four magnetic materials. — Iron, steel, nickel, cobalt. Define a magnetic field. — Region where a magnet or magnetic material feels a force. Direction of field lines outside a magnet? — From north pole to south pole. Where is a magnet's field strongest? — Where the field lines are closest, at the poles. What is a compass needle? — A small magnet free to turn. Define an electromagnet. — A coil carrying current, usually on an iron core. Name three ways to strengthen an electromagnet. — More turns, more current, iron core. What happens if electromagnet current reverses? — Its poles swap. Keep going with Lina
