Explain Energy Transfer Via Fields Practice Test

A straight conductor of length $L=0.50\ \text{m}$ carries current $I=2.0\ \text{A}$ in a uniform magnetic field $B=0.20\ \text{T}$ oriented for maximum force. The wire is constrained so it does not move. Which statement about energy transfer by the magnetic field is correct in this situation?

A student claims that wireless charging works because “electricity flows through the air from the pad into the phone.” Which response correctly distinguishes field-mediated energy transfer from direct contact conduction?
