What is the term for the effect where a current in a wire in a magnetic field creates a magnetic field and can repel a magnet, enabling energy generation?

What is the term for the effect where a current in a wire in a magnetic field creates a magnetic field and can repel a magnet, enabling energy generation?

• A. Magnetic Effect
• B. Electromagnetic Induction
• C. Physiological Effect
• D. Direct Current

Answer: (A)

When current flows through a wire, it creates its own magnetic field around the conductor. This magnetic field can interact with a nearby magnet, producing a force that can push or repel the magnet. That interaction is the magnetic effect of a current, and it’s what underpins energy-transfer devices like motors and generators: the magnetic fields exchange energy as forces act. Electromagnetic induction, by contrast, refers to generating current from changing magnetic flux, not simply the field produced by an existing current. The term described here is Magnetic Effect.
