Question

nolan set up the equipment shown in order to induce a current in a wire. which best explains why no current is induced? the wire needs to be coiled less tightly. the wire needs to be straight, not coiled. the magnet needs to be moved through the coils of wire. the magnet needs to be held above the coils of wire.

Explanation:

Electromagnetic induction requires a changing magnetic - flux through a conductor. Moving a magnet through the coils of wire changes the magnetic - flux and can induce a current. Keeping the magnet stationary relative to the coils does not create a changing magnetic - flux and thus no current is induced.

Answer:

The magnet needs to be moved through the coils of wire.
