4EJ523 ELECTROMAGNETIC DEVICES CW1 and CW2
- A) Write a maximum of 2 pages on each of the following:
- Scalar and vector fields
- Electrostatic fields around multiple point sources
- Magnetic material and magnetic circuits
- Permanent and electromagnets
- Ampère’s force law
- Magnetic field within a linear and a toroidal coil

In each of the above topics, give a numerical example to demonstrate its application.
- B) Study of Speed-Torque Characteristics of Separately Excited DC Shunt Motor
Carry out an experimental investigation by following out the attached experimental sheet (DC experiment).
Assignment 2
Carry out an experimental investigation by following out the attached experimental sheet (Transformer experiment) on each of the short circuit, open circuit and load tests.
- A) Write a maximum of 2 pages on each of the following:
- Scalar and vector fields
Vector and scalar fields, physical and mathematical importance and gradient identification, separation. Introduction to incorporate these scientific principles, observations and methods of Electromagnetism.
Scalar field is a field with a single number correlated with each point. Air. Air. We’ve shown the Earth’s surface atmosphere temperature is one. Scalar field proof.
In vector calculus and physics, a vector field is a function assignment to each point in a space subset. A vector field in the plane (e.g.) may be represented as a series of arrows with a specified magnitude and distance, each connected to a point in the sky.
Magnetic force is a line that has both orientation and magnitude. The amplitude depends on the field lines and the distance from the north pole to the south.
