Fig 4 Fig 3. 6. In Fig 4, (1) write down the expression of the current, as a function of time in the left circuit,...
TA) Q4: Time (30 minutes) A. The current flowing in a solenoid, of 400 turns, 20 cm length & 4 cm diameter, changes with time according to the graph show to right. Derive an expression for the strength of the induced electric field inside the solenoid 0 00 01 02 03 04 Sketch the corresponding graph showing how the induced electric field vary with time. B. The Figure to right shows an infinite straight wire carries a current I is...
Pre-Laboratory Work 3 (estimated time 1 hour) In reality, when a circuit is first connected to a power source the current through the circuit does not jump discontinuously from zero to its maximum value. Instead, the current increases smoothly due to the effect known as self-induction. The circuit itself can be seen as a current loop and as the current increases with time, the magnetic fields circling the wires become stronger. Thus, the magnetic flux through the loop itself increases,...
Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected? (b) If while travelling 0.200 m, with...
please show work when possible so that I may better understand. Thank you. x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...
