What method of making magnets is illustrated in setups A and B? Give the names of the parts of the current labelled I, II, and III in set-up B. How will you know the steel bar and iron bar 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: i) The method 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: ii) 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: iii) You will know the steel bar and iron nail are magnetized if they: Attract small magnetic materials* such as iron filings, paper clips, or pins. Repel a known pole* of another magnet (this is the most conclusive test). Question 4: iv) Another method of making magnets is the: Induction method* (placing a magnetic material in contact with or near a strong magnet). Question 5: v) When the north pole of the bar magnet and the north pole of the steel bar are brought together: They will repel* each other.
