Educational worksheet on magnetism featuring exercises on attraction/repulsion, magnetic fields, and electromagnet components.

Let’s go step by step through each section.

Section 3: State whether these magnets would attract or repel.

We use the rule:
→ Opposite poles (N-S or S-N) attract
→ Same poles (N-N or S-S) repel

1. First pair:
Left magnet: S — N → right end is N
Right magnet: S — N → left end is S
So, N faces S → Attract

2. Second pair:
Left magnet: S — N → right end is N
Right magnet: N — S → left end is N
So, N faces N → Repel

3. Third pair:
Left magnet: N — S → right end is S
Right magnet: S — N → left end is S
So, S faces S → Repel

Wait — let me double-check #3:

Left magnet: N on left, S on right → so right face is S
Right magnet: S on left, N on right → so left face is S
Yes, S facing S → Repel

But wait — look at the arrows in the diagram for #3: they are pointing away from each other? That might be a hint, but we should go by pole alignment.

Actually, let’s re-express all clearly:

Pair 1:
Magnet A: [S | N] → N is on right
Magnet B: [S | N] → S is on left
So N (from A) faces S (from B) → Opposite → Attract ✔

Pair 2:
Magnet A: [S | N] → N on right
Magnet B: [N | S] → N on left
So N faces N → Same → Repel ✔

Pair 3:
Magnet A: [N | S] → S on right
Magnet B: [S | N] → S on left
So S faces S → Same → Repel ✔

All correct.

Section 4: Fill in the blanks using word bank: Permanent, Attract, Temporary, Repel, Poles, Field

1. The opposite poles of a magnet will ______ each other.
→ Opposite poles attract → Attract

2. If two south poles of a magnet are placed together, they will ______ each other.
→ Same poles repel → Repel

3. The area around a magnet which the magnetic strength is felt is called the magnetic ______.
→ That’s the definition of magnetic field → Field

4. The magnetic field is strongest at the ______.
→ Strongest at the poles → Poles

5. ______ magnets lose its magnetism (demagnetize) when its power source is removed.
→ These are temporary magnets (like electromagnets) → Temporary

6. ______ hold their magnetism for a very long period of time.
→ Permanent magnets → Permanent

All fit perfectly.

Section 5: Label the parts of the electromagnet.

Diagram shows:
- Battery → connected to wire coiled around nail
- Nail has N and S marked at ends
- Three labels needed:

Left box points to battery → that’s the power source or just “battery” — but since it’s labeling parts of the *electromagnet*, maybe “battery” is acceptable. But typically, the three main parts are:
1. Power source (battery)
2. Coil (wire wrapped around core)
3. Core (the iron nail)

Looking at arrows:

→ Left arrow points to battery → label: Battery (or Power Source)

→ Top-right arrow points to the coil/wire near top of nail → label: Coil or Wire

→ Bottom-right arrow points to the nail itself → label: Iron Core or just Core

But since this is for school level, likely expected answers:

- Battery → Battery
- Wire wrapped around nail → Coil
- Nail → Core

Sometimes “electromagnet” refers to the whole setup, but here we’re labeling parts.

Also note: the nail becomes magnetized only when current flows — so it’s the core.

Final labels:

Left box (pointing to battery): Battery
Top right box (pointing to wire/coil): Coil
Bottom right box (pointing to nail): Core

Alternatively, some curricula say:

- Power source
- Conductor (wire)
- Ferromagnetic core

But for simplicity and matching typical elementary/middle school level:

✔ Battery
✔ Coil
✔ Core
