HC Verma Class 12 Physics Solutions Chapter 38: Electromagnetic Induction

About the chapter: HC Verma Solutions Class 12 Physics Chapter 38

There are a total of 98 questions in the HC Verma Class 12 Physics Solutions Chapter 38- Electromagnetic Induction. Every question is answered step by step, with a full explanation of how the ideas in the question are used. Most of the questions are based on numbers and derivations, which require a strong understanding of the ideas covered in Electromagnetic Induction. It is important to always understand and remember the ideas.

Conducting Rod:

A conducting rod of length 1 is turned at a constant angle around the axis that goes through its fixed end and is perpendicular to its length. The magnetic field (B) is in the same direction as the plane of the paper. generated emf across the ends of the rod, where v is the frequency (number of turns per second) and T is the time period.

Cycle Wheel:

A conducting rod of length 1 is turned at a constant angle around the axis that goes through its fixed end and is perpendicular to its length. The magnetic field (B) is in the same direction as the plane of the paper. generated emf across the ends of the rod, where v is the frequency (number of turns per second) and T is the time period.

Producer of the Faraday Copper Disc:

When a metal disc spins in a transverse magnetic field, the radial conductors cut the magnetic field lines. This makes each emf’ e have the same number of identical cells.

where e=12 Bωr2

Semi Circular Conducting Loop:

If you have a semicircular conducting loop (ACD) with a radius of r′’ and a center at O, the plane of the loop is in the plane of the paper. Now, the loop is turned at a constant speed around an axis that goes through O and is parallel to the paper plane. The resistance of the loop is R.

Inductance:

• Inductance is a property of an electric circuit that makes it resist any change in the flow of electricity through it.
• Inductance is something that all electrical circuits have in common. Whether we want it or not, it will always be in an electrical circuit.
• If there is no iron in the circuit, a straight wire carrying electricity will have less inductance.
• In an electrical circuit, inductance works against any change in the current. This is similar to how inertia works in mechanics.
