Electromagnetism MCQs from the MDCAT past papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · MDCAT 2025 · Electromagnetism
The wave with the highest frequency and penetrating power is:
- A.X-rays
- B.Ultraviolet rays
- C.Gamma rays
- D.Microwaves
Show answer
Answer: C. Gamma rays — Gamma rays have the highest frequency and greatest penetrating power.
- Q2 · MDCAT 2024 · Electromagnetism
The formula φ = B.A represents
- A.Electric flux
- B.Magnetic flux
- C.Electric flux density
- D.Gravitational flux
Show answer
Answer: B. Magnetic flux — φ = B·A represents magnetic flux.
- Q3 · MDCAT 2023 · Electromagnetism
A charged particle moves in a uniform electric field between two oppositely charged parallel metal plates. To calculate the force acting on the particle due to the electric field, which quantity is not required?
- A.Particle charge
- B.Particle speed
- C.Plate separation
- D.Potential difference between the plates
Show answer
Answer: B. Particle speed — To calculate the electric force on a charged particle between parallel plates, you don't need to know the particle's speed — only its charge and the field strength (from plate separation and potential difference).
