Electromagnetic Induction

Question 10 • TX-Physics B

Which change would reverse the direction of the electric current generated through electromagnetic induction?

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

Explanation

The direction of induced current depends on the direction of the changing magnetic field through the coil. Using the magnet’s opposite pole reverses the magnetic field direction, so the induced current reverses as well. Moving the magnet slower, adding more loops, or using a weaker magnet can change the current’s size, but not its direction.
