Magnetism and Electromagnetism — JAMB Physics Past Questions
Magnetism and Electromagnetism is one topic inside the JAMB Physics syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Magnetism and Electromagnetism questions with worked answers.
When JAMB examined Magnetism and Electromagnetism
Magnetism and Electromagnetism questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

A transformer has 100 turns in its primary coil and 500 turns in its secondary coil. If the input voltage is 240 V, what is the output voltage?
- A 48 V
- B 1200 V
- C 240 V
- D 600 V
Answer: B
Transformer equation: Vₛ/Vₚ = Nₛ/Nₚ → Vₛ = 240 × (500/100) = 1200 V.
Two transformers are identical, except that the first has a solid iron core, while the second has a laminated iron core. What is the major disadvantage of the first when compared with the second?
- A The second will tend to overheat.
- B The second is less efficient.
- C The first will tend to overheat.
- D There is no disadvantage.
