The correct answer is **B. Movement of charged particles through the wire**.
The magnetic force of an electromagnet is produced by the flow of electric current through the wire, which consists of moving charged particles (electrons). This current generates a magnetic field around the wire, thus creating the electromagnet's magnetic force.
