Text Solution
Verified by ExpertsThe correct answer is:
B
The induction coil, also known as a transformer or an induction transformer, works primarily on the principle of mutual induction.
Step 1: Understand that mutual induction occurs when the magnetic field generated by a current flowing through one coil induces a voltage in a nearby coil.
Step 2: The induction coil consists of two coils of wire placed close to each other. When an electric current passes through the primary coil (the first coil), it creates a magnetic field.
Step 3: This changing magnetic field induces a voltage in the secondary coil (the second coil) based on Faraday's law of electromagnetic induction.
Step 4: The efficiency of this process is enhanced by using a core material, typically made of iron, which increases the magnetic coupling between the two coils.
Therefore, the correct answer is mutual induction.
