To a magnetic core, with a relative permeability of 2100, a current I1 of 1 A and a current I2 of 2 A are applied, where the number of turns of the winding is 1000. The depth of the magnetic core is 20 cm. take into account that the bounded measurements are given in centimeters. The air gap shown in the figure is 0.2 cm and has an effective area equivalent to 1.1 times the cross-sectional area of the core. Determine:a) The equivalent circuit with sources and reluctance (Graph it)b) The magnetic flux of the central columnc) Magnetic induction at point Ad) Explain what would happen if the flow of current I1 is reversed

Pr1. A metal rod having a mass m and length e has resistance R. The rod hangs from two vertical metallic wires of length l in a uni- form vertical magnetic field B of a horseshoe magnet (see figure). The wires have negligib- le resistance. An AC voltage source is connec- ted between the wires which provides a voltage U(t) = Uo cos wt, where Uo and w are constants. U(t) S m IN a) Show that for small angular displacements p the motion of the rod can be described by the cquation U (t) = aö + Bộ + VP, and express the constants a, 3, y in terms of quantities m, l, B, R and the gravitational ac- celeration g. b) At a certain frequency w = wo the ampli- tude of the oscillations of the rod becomes large and the equation above does not describe the motion anymore. Estimate the frequency wo.
I would be very pleased if a return is provided as soon as possible.
An electromagnet is used to support a solid piece of steel, as shown in the figure below. A force of 10,000 N is required to support the weight at a distance of x=0.5m. The cross-sectional area of the magnetic core (the fixed part) is 0.01m2. The coil has 1,000 turns. Assume negligible reluctance in steel and negligible fringing in the air gaps. Fixed fe Movable Determine: 1. The current required to lift the weight | 2. The minimum current required to keep the weight from falling for x = 1.0 mm. Assume negligible reluctance in steel and negligible fringing in the air gaps. Assumptions: Negligible reluctance for the steel parts and negligible fringing in the air gaps.
A solenoid of 100 turns has a length of 75 cm and the radius of 20 cm. A steel rod of circular cross-section is fitted in the solenoid coaxially. Relative permeability of steel is 3000 and a dc current of 10 A is passed through solenoid. Conclude the inductance of the system, energy stored and the mean flux density inside the solenoid.

A conducting rod is free to slide on two parallel conducting bars. A resistor is connected to the end of the bar. The conducting bar and the rod have negligible resistance. A constant magnetic field is directed perpendicularly into the page. The power dissipated in the resistor is 64 W. The constant speed of the rod is v=8.00 m/s.
