Electromagnetic Induction

Question 1 • (OC27) Earth/Space Sci-2001310-S2-Nelson

Which change will cause an increase in the electric current produced through electromagnetic induction?

Answer
A
using more wire loops in the solenoid
B
using the opposite pole of the magnet
C
using a weaker magnet
D
moving the solenoid slower

Explanation

A changing magnetic field induces a voltage in a coil, and more wire loops make the induced voltage larger. With the same circuit resistance, the larger voltage produces more current. Using the opposite pole reverses the current’s direction, while a weaker magnet or slower motion reduces the change in magnetic flux.
