← ScienceWhich mechanism suppresses arc formation when relay contacts separate?
A)Contact-quenching magnetic field induction✓
B)Increased capacitive load discharge
C)Decreased atmospheric gas pressure
D)Contact surface area extension
💡 Explanation
Magnetic field induction suppresses arcs because the collapsing magnetic field generates a reverse voltage that opposes the arc current. Therefore, arc formation minimizes rather than enhancing current because alternative factors aren't present.
