Question 3 • FL-2003310-Physical Science CR

A current is induced in a wire by moving the wire through a magnetic field. Which is one factor that affects the direction of the current?

Answer
A
the direction in which the wire moves
B
the thickness of the wire
C
the direction of the needle on an ammeter
D
the type of magnet

Explanation

The direction of the induced current depends on how the wire moves through the magnetic field. Reversing the wire’s motion reverses the direction of the current. Wire thickness can affect the current’s size, but it does not determine its direction.
