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.
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) momentum but not energy b) neither moment
Find the lowest frequency for which destructive interference Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m
Capacitors: When a voltage is applied to a capacitive circuit there is a change in the electric flux. The ease with which this change takes place is a measure of the capacitan
