1.5: Exercises (2) 6. An electromagnet shown below has a core of effective length 610 mm and a cross-sectional area of 520 mm2. A rectangular block of steel of mass 2.5 kg is attracted by the electromagnet's force of alignment when its 300-turn coils are energized. The magnetic circuit is 220 mm long and the effective cross-sectional area is also 520 mm2. If the relative permeability of both core and steel block is 750, estimate the coil current. Neglect frictional losses and assume the accelerationgdue &ogravity as Power Source laz 300 Turns Electromagnet Rectangular Steel Block
