Magnetic poles, fields and compasses
Electricity and magnetism
CCSS NGSS.MS-PS2-3CCSS NGSS.MS-PS2-5England: KS3 Physics: Electricity and electromagnetism (magnetism)
Objective and success criteria
Students will: Magnetic poles, fields and compasses.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Magnets and magnetic materials
Leads to: The motor effect (F = B I l) and Fleming's left-hand rule
Materials: Circuit kits (cells, wires, bulbs), Circuit symbol cards, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Magnets and magnetic materials). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- The north pole of one magnet is brought near the north pole of another. Do they attract or repel? (attract / repel) → repelPrompt: Like poles repel; unlike (opposite) poles attract.
- Is a plastic spoon attracted to a magnet? (magnetic / not magnetic) → not magneticPrompt: Only a few metals are attracted to magnets.
- How could you test which of two magnets is stronger? (count how many paper clips each can hold in a chain / see which is heavier / see which is shinier / see which is longer) → count how many paper clips each can hold in a chainPrompt: A stronger magnet can hold more.
Hook · 5 min
- Show a circuit with a gap and ask why the bulb doesn't light.
- Share the objective: Magnetic poles, fields and compasses. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: The north pole of one magnet is brought near the south pole of another. What happens?
- Step 1: Unlike poles attract.
- Step 2: So the answer is: they attract
- Answer: they attract
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- The south pole of one magnet is brought near the south pole of another. What happens? (they attract / they repel) → they repelPrompt: Like poles behave differently from unlike poles.
- Which way do magnetic field lines point outside a bar magnet? (from the north pole to the south pole / straight up / in circles around the middle / from the south pole to the north pole) → from the north pole to the south polePrompt: A compass needle follows the field lines.
You do: independent practice · 10 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which way do magnetic field lines point outside a bar magnet? (from the south pole to the north pole / straight up / in circles around the middle / from the north pole to the south pole) → from the north pole to the south polePrompt: A compass needle follows the field lines.
- Magnets: which statement is NOT true? (Magnetic field lines cross each other. / Magnetic fields can pass through paper and plastic. / Iron, nickel and cobalt are magnetic materials. / A magnet always has both a north and a south pole.) → Magnetic field lines cross each other.Prompt: What happens if you cut a magnet in half?
Watch out for
- Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
- Remembering facts without the reason: ask "why?" and "what is the evidence?"
Support and stretch
Support
- Review first: Magnets and magnetic materials.
- Use concrete materials: circuit kits (cells, wires, bulbs).
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Move on to: The motor effect (F = B I l) and Fleming's left-hand rule.
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
