Before making current in a coil, the current is zero and active before breaking the current is maximum, in other words, it is constant in both the cases, obviously on making changing or breaking the current in a ciruit, the current stants changing. The changing current produces changing magnetic bielo. which in turn produces induced current neighbouring coil of the circuit.
In each of the following questions a statement of Assertion is given f...
Assertion: Making or breaking of current in a coil produces no momentary current in the neighboring coil of another circuit.
Reason: Momentary current in the neighboring coil of another circuit is an eddy current.
Explanation:
The given assertion and reason are related to the phenomenon of electromagnetic induction.
Electromagnetic Induction:
Electromagnetic induction is the process of generating an electromotive force (emf) or voltage across a conductor when it is exposed to a changing magnetic field. This phenomenon was discovered by Michael Faraday and is based on Faraday's law of electromagnetic induction.
Faraday's Law of Electromagnetic Induction:
According to Faraday's law, the magnitude of the induced emf in a circuit is directly proportional to the rate of change of magnetic flux through the circuit. It can be mathematically expressed as:
EMF = -dφ/dt
where EMF is the induced electromotive force, dφ/dt is the rate of change of magnetic flux.
Explanation of Assertion and Reason:
The given assertion states that making or breaking of current in a coil produces no momentary current in the neighboring coil of another circuit. This is because the changing current in one coil does not directly induce a momentary current in the neighboring coil.
The reason given for the assertion states that the momentary current in the neighboring coil of another circuit is an eddy current. However, this reason is incorrect. Eddy currents are induced currents that circulate within a conductor due to a changing magnetic field. They are not specifically related to the momentary current induced in a neighboring coil due to the making or breaking of current in another coil.
Conclusion:
Hence, the correct answer is option (c) If Assertion is true but Reason is false.
