Magnetic Flux Inside an Exciting Coil
The correct statement among the given options is C, which states that the magnetic flux inside the exciting coil is greater than that on its outside surface. Let's understand why it is so.
Explanation:
- Magnetic flux is the measure of the magnetic field passing through a surface. It is represented by the symbol Φ and its unit is Weber (Wb).
- When an electric current flows through a conductor, it generates a magnetic field around it. This magnetic field is proportional to the current and is measured in Tesla (T).
- An exciting coil is a type of electromagnet that is used to create a magnetic field. It consists of a coil of wire, through which an electric current is passed to produce a magnetic field.
- When current flows through the exciting coil, it generates a magnetic field around it. This magnetic field passes through the coil itself as well as its surrounding space.
- According to Faraday's law of electromagnetic induction, the magnetic flux passing through a closed surface is proportional to the induced electromotive force (EMF) in a conductor. This means that if the magnetic flux passing through a surface changes, then an EMF is induced in any conductor that is located within that surface.
- In the case of an exciting coil, the magnetic flux passing through its inner surface is greater than that passing through its outer surface. This is because the magnetic field generated by the current in the coil is concentrated within the coil itself, and gradually decreases as we move away from the coil. Hence, the magnetic flux passing through the inner surface of the coil is greater than that passing through its outer surface.
- This also means that if a conductor is placed within the exciting coil, it will experience a higher induced EMF than if it were placed outside the coil. This property is used in devices such as transformers, where a conductor is placed within the coil to transfer energy from one circuit to another.
Conclusion:
Hence, option C is the correct statement as the magnetic flux inside the exciting coil is greater than that on its outside surface.
