Amagnetic compass is placed near an insulated copper wire. when the wire is connected to a battery and a current is created, the compass needle moves and changes its position. which is the best explanation for the production of a force that causes the needle to move?
(1)the copper wire magnetizes the compass needle and exerts the force on the compass needle.
(2)the compass needle magnetizes the copper wire and exerts the force on the compass needle.
(3)the insulation on the wire becomes charged, which exerts the force on the compass needle.
(4)the current in the wire produces a magnetic field that exerts the force on the compass needle.

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
