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
