The diagram shows a setup for inducing a current in a wire. which change would cause the needle on the ammeter to point to the left of the zero? making the wire thicker adding coils to the wire disconnecting the wire from one end of the ammeter moving the wire downward through the magnetic field

the answer is; moving the wire downward through the magnetic field.

when the coil is moved towards the magnet, the pointer moves in one direction of the zero. conversely, when the coil is moved away from the magnet, the pointer moves in the opposite direction of the zero.   the rate at which this movement occurs also determines the size of the emf induced in the coil.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

i think it would be 5
