What method of making magnets is illustrated in set-ups A and B? Give the names of the parts of the circuit labelled i, II, and III in set-up B. How will you know the steel bar and iron nail are magnetized? Name any other method of making magnets. What will happen when the north pole of the bar magnet and the north pole of the steel bar are brought together?

Here are the answers to the questions: Question 1: The methods of making magnets illustrated in set-ups A and B are: Set-up A: Stroking method* (or single touch method). Set-up B: Electrical method* (or electromagnetism). Question 2: The names of the parts of the circuit labelled I, II, and III in set-up B are: I: Power source* (e.g., battery or cell) II: Switch* III: Coil of wire* (or solenoid) Question 3: You will know the steel bar and iron nail are magnetized if they: Attract small magnetic materials* (e.g., iron filings, pins). Repel a known pole* of another magnet. Question 4: Another method of making magnets is the: Induction method*. Question 5: When the north pole of the bar magnet and the north pole of the steel bar are brought together: They will repel* each other.
