Which outcome occurs when a radio antenna induces current?

💡 Explanation

Electromagnetic wave propagation occurs because a fluctuating electric field induces a magnetic field, and the reverse also happens. This is electromagnetic induction; therefore, electromagnetic energy radiates away, rather than current dissipation which happens with resistance.
