Monday 4thJanuary 2021 Magnets Starter: True or False? 1 All metals are magnetic. 2 All magnets have a north and south pole. 3 The earth has its own magnetic field. 4 Like poles attract. 1. Opposite poles attract. 5 1. The earth has a magnetic core. 6 Extension Question: What else do you know about magnets?
Starter: True or False? 1 false All metals are magnetic. All magnets have a north and south pole. 2 true 3 The earth has its own magnetic field. true 4 Like poles attract. false 1. Opposite poles attract. 5 true 1. The earth has a magnetic core. 6 true
Watch the video and attempt the questions below: What happens to a metal object that enters the magnetic field of a magnet? What happens to a wooden object that enters the magnetic field of a magnet? Name 3 magnetic objects and 3 non-magnetic objects What is meant by the term magnetic object ?
Most materials are not magnetic, but some are. A magnetic material can be magnetized (made into a magnet) or will be attracted to a magnet. These metals are magnetic: Iron Cobalt Nickel Steel is mostly iron, so steel is magnetic too. Here are some examples of magnetic objects:
Magnetism is an invisible non-contact force (which means the objects dont need to touch for the force to work). All magnets have a north (N) and a south (S) pole. Like poles repel. This means that the two poles will push away from each other. Opposite poles attract. This means that the invisible magnetic force between the magnets will pull the poles together.
Will these magnets attract (pull together) or repel (push apart)? Draw diagrams 1-3 and state whether the magnets would attract or repel. 1. 2. 3.
Will these magnets attract (pull together) or repel (push apart)? 1. Repel 2. Repel 3. Attract Attract
Check your knowledge of magnets. Use the keywords to help you fill in the blanks. Keywords repel cobalt attracted away north south magnetic force opposite Magnets have two poles. One end of a magnet is called the pole and the other end of a magnet is called the pole. poles attract. This means that the between the magnets will force the poles together. invisible Like poles will push . This means that the two poles from each other.
