Assignment Report Q1. For the Magnetic circuit shown in Fig. 5.1, relative permeability of the core material is 6000, its rectangular cross section is 2 cm by 3 cm. The coil has 500 turns and the core thickness is 3 cm. If flux density in the gap is 0.25 T. Find the following: a) The gap reluctance (assume that fringing increases effective cross-sectional area of air gap by 50%). b) The required airgap mmf. c)...

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...

Problem 5: A 5 cm long wire is in a uniform magnetic field of 4T, so that current in the wire is perpendicular to the magnetic field. The wire is connected to a 10 ohm resistor in series, so that the resistance of the wire is negligible. The wire and resister are then connected in series to a charged 1500mF capacitor at 50 kV. A: What is the current through the wire as function of time, with t-0 being when...
