Final answer:
When a magnet is thrust into a coil of wire, it induces both current and voltage through electromagnetic induction.
Step-by-step explanation:
The correct answer is C. Both of these. When a magnet is thrust into a coil of wire, it induces both current and voltage. This phenomenon is known as electromagnetic induction. As the magnet moves through the coil, the changing magnetic field creates a current, which in turn generates a voltage across the coil. This process is the basis of many electrical devices, such as generators and transformers.
