Year 7 Science — Exploring magnets

Sort materials into magnetic and non-magnetic, find the poles of a magnet, and work out what happens when two magnets are brought together.

Name: ________________________

  1. 1.Which of these is a shape the chapter names for a magnet?

    • a) A cone magnet
    • b) A ring magnet
    • c) A spiral magnet
    • d) A cube magnet

  2. 2.A piece of wood is slipped between a bar magnet and a compass needle. What happens to the needle's deflection?

    • a) It doubles, because wood strengthens the magnet
    • b) It stops at once, because wood blocks magnets
    • c) It stays much as it was — the magnet's effect reaches through the wood
    • d) The needle turns to point at the wood instead

  3. 3.Match each term to what it means.

    • Non-magnetic material
    • Magnetic material
    • Magnetic compass
    • drawn towards a magnet
    • points along north-south
    • left alone by a magnet

  4. 4.A magnet is brought near each of these materials. Sort them by whether it draws them towards itself.

    Groups: Magnetic · Non-magnetic

    • Cobalt
    • Plastic
    • Nickel
    • Wood
    • Cardboard
    • Iron
    • Glass

  5. 5.A magnet has two of these, and the chapter calls one of them North and the other South. What is the word for them?

  6. 6.Iron filings are scattered under this bar magnet. Tap the part where the fewest of them would stick.

    Write the number of the part.

    123

  7. 7.Two magnets are brought close, pole to pole. Sort each pairing by what it does.

    Groups: Attract · Repel

    • Two like poles, South facing South
    • Two unlike poles, South facing North
    • Two unlike poles, North facing South
    • Two like poles, North facing North

  8. 8.A magnet hangs from a thread and is free to turn. It settles along a line joining which two directions? Answer with both, joined by a hyphen.

Answer key — Year 7 Science — Exploring magnets

  1. 1. b) A ring magnet
  2. 2. c) It stays much as it was — the magnet's effect reaches through the wood
  3. 3. Non-magnetic material → left alone by a magnet; Magnetic material → drawn towards a magnet; Magnetic compass → points along north-south
  4. 4. Iron → Magnetic; Nickel → Magnetic; Cobalt → Magnetic; Wood → Non-magnetic; Plastic → Non-magnetic; Glass → Non-magnetic; Cardboard → Non-magnetic
  5. 5.
    • poles
    • pole
  6. 6. 2 — The middle
  7. 7. Two like poles, North facing North → Repel; Two like poles, South facing South → Repel; Two unlike poles, North facing South → Attract; Two unlike poles, South facing North → Attract
  8. 8.
    • north-south
    • south-north
