Given below are two statements:
Statement (I): When currents vary with time, Newton's third law is valid only if momentum carried by the electromagnetic field is taken into account.
Statement (II): Ampere's circuital law does not depend on Biot-Savart's law.
In the light of the above statements, choose the correct answer from the options given below:

Question

Given below are two statements:

Statement (I): When currents vary with time, Newton's third law is valid only if momentum carried by the electromagnetic field is taken into account.

Statement (II): Ampere's circuital law does not depend on Biot-Savart's law.

In the light of the above statements, choose the correct answer from the options given below:

G1 Physics · Accepted Answer

Statement I is true: for time-varying electromagnetic systems, field momentum must be included in momentum conservation. Statement II is false in the context of magnetostatics because Ampere's circuital law is consistent with and can be derived from the magnetic field relation represented by Biot-Savart law. Hence: Statement I is true but Statement II is false.
