Question

Magneto breaker points must be timed to open when the

a. Rotating magnet is positioned a few degrees before neutral
b. Greatest magnetic field stress exists in the primary circuit
c. Rotating magnet is in the full register position

Answer 1

The correct answer is 'a. the magnetic flux is at a maximum'.

Step-by-step explanation:

The correct answer is a. the magnetic flux is at a maximum.

According to Faraday's law of electromagnetic induction, the magnitude of the induced electromotive force (emf) in a coil is directly proportional to the rate of change of magnetic flux through the coil.

The maximum emf occurs when the magnetic flux is changing at its maximum rate, which happens when the magnetic flux is at a maximum.
