GCSE Physics - The motor Effect and
Electric motors (AQA) Final Review
Exam And All Correct Answers.

What is the motor effect? - Answer A force experienced by a current-carrying wire in a magnetic field



What happens when a wire carrying a current is exposed to the magnetic field of another magnet? -
Answer A force is produced perpendicular to the direction of the magnetic field produced. This is the
motor effect



What equation calculates the force produced by the motor effect - Answer Force = magnetic flux
density (T) x current(A) x length (m)



What is the magnetic flux density? - Answer A measure of the strength of the magnetic field



What are the 3 factors that affect the size of the force of a wire? - Answer - The magnetic flux density

- Current

- Length of the wire



In Flemings left hand rule what does your thumb, middle finger and index finger represent? - Answer -
Thumb = Direction of the force

- Index finger = Direction of the magnetic field

- Middle finger = Direction of current



What happens when the wire carrying the current is coiled? - Answer The motor effect acting on it
causes the wire to rotate



What happens as current flows from negative to positive in an electric motor? - Answer The force
produced in each side of the coil acts in the opposite direction causing the coil to rotate overall
