1 Magnetism – Making Magnets
WALT: State which materials are magnetic and describe how to make a magnet I must be able to state the 4 materials that can be magnetic I should be able to describe how to make a magnet I could accurately draw a magnetic field around a bar magnet (with arrows)

2 Magnetism

3 Magnetic or not? Iron Aluminium Magnesium Cobalt Copper Steel Nickel

4 Lesson Outcomes What materials are magnetic? Low level
What two things can magnetic poles do? What are domains? How can you make a magnet? What is a magnetic field? Draw and explain the magnetic field around a bar magnet. How do compasses work? High level

5 Bar Magnet S N

6 Like poles repel, unlike poles attract
Use the magnets on your desk to answer “attract” or “repel” to the next slide…………….

7 Attraction or Repulsion?

8 How could you turn a piece of iron into a magnet?

9 S N

11 Draw and label the points of a compass.

12 In fact, if you hang your bar magnets from a piece of string, they will align themselves North-South
You can do this if you have time in a minute…

13 Earth – a Giant Magnet Animation

14 You are now going to make your own compasses
You have 5 minutes to make a compass from your iron nail Write down what you did and draw a diagram (like Step 2 – on right)

15 Magnetic Fields Explain

16 Please turn to page 310-311 How could we summarise this?
Magnetism is a force Iron filings can show us the magnetic field Let’s have a go at finding the magnetic field of your magnets with iron filings. Draw a diagram like the ones on the slides below. MAKE SURE YOU MARK ON ARROWS IN THE CORRECT DIRECTION
