A section through a magnetic circuit of uniform cross-sectional area 2cm2 is shown in figure.
The cast steel core has a mean length of 25cm. The air gap is 1mm wide and the coil has 5000 turns.
The B-H curve for cast steel. Verify the current in the coil to produce a flux density of 0.80 T in the air gap, suppose that all the flux passes by both parts of the magnetic circuit.
A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V. The secondary winding gives a full load current of 30A at a power factor of 0.8 l

Here's what is given: A. There are three 1 meter sticks B. There are four weights: Weight #1 = 1kg Weight #2 = 1.2kg Weight #3 = 1.5kg Weight #4 = 2kg The sticks don't hav
Weber; Wb (after W. Weber, 1804-1891): The derived SI unit of magnetic flux equivalent to the flux that, relating a circuit of one turn, generates in it an electromotive force
What is a light Guide? While a number of single fibers are grouped together to create a larger diameter light conductor the resulting structure is termed as a light guide. Occa
A popular toy on the market some years ago was the water rocket. Water (at 10°C) was loaded into a plastic rocket and pressurized with a hand pump. The rocket was released and woul
