1. How can a wire and a magnet create an electric current?
**Either a or b will produce an electric current.**
(This is based on the principle of electromagnetic induction, where either moving the magnet inside a coil of wire or moving the coil through a magnetic field can generate an electric current.)
2. Two objects will experience an electric force of attraction when they have _________.
**opposite charges.**
(Like charges repel each other, while opposite charges attract each other.)
3. If the distance between two charged objects increases, the electric force between them ____________.
**decreases.**
(The electric force between charged objects is inversely proportional to the square of the distance between them, so as the distance increases, the force decreases.)
