EMF(Electromagnetic Field Theory), Mid-2 Previous year Question paper, R23 regulation

EMF MID-2 Previous year  Question paper R23 regulation 

  Hi, here we have the EMF Mid-2 PYQ (Previous Year Question Paper). The Mid-2 exam mainly focuses on three units:

➡️ Magnetostatics, Ampere’s Law and Force in Magnetic Fields
➡️ Self and Mutual Inductance
➡️ Time Varying Fields

Now, let's first look at the concepts covered in each unit.

UNIT - III

Magneto statics, Ampere’s Law and Force in magnetic fields:

Biot-Savart’s law and its applications viz. Straight current carrying filament, circular, square, rectangle and solenoid current carrying wire- Magnetic flux density and Maxwell’s second Equation, Ampere’s circuital law and its applications viz. MFI due to an infinite sheet, long filament, solenoid, toroidal current carrying conductor, point form of Ampere’s circuital law, Maxwell’s third equation.

Magnetic force, moving charges in a magnetic field- Lorentz force equation, force on a current element in a magnetic field, force on a straight and a long current carrying conductor in a magnetic field, force between two straight long and parallel current carrying conductors, Magnetic dipole, Magnetic torque and moment.

UNIT - IV

Self and mutual inductance:

Self and mutual inductance – determination of self- inductance of a solenoid, toroid, coaxial cable and mutual inductance between a straight long wire and a square loop wire in the same plane – Energy stored and energy density in a magnetic field.

UNIT - V

Time Varying Fields:

Faraday’s laws of electromagnetic induction, Maxwell’s fourth equation, integral and point forms of Maxwell’s equations, statically and dynamically induced EMF, Displacement current, Modification of Maxwell’s equations for time varying fields, Poynting theorem and Poynting vector.
