Assume you have a solenoid with a diameter of 4.0 cm and 2900 turns per meter, with an impedance of 0.70. An iron core consisting of a bundle of wires is placed in the core. The core has an effective susceptibility of 10 (rather than 1000, for this is based on experimental results). An aluminum ring of a mass of 23 grams (1.4 cm length and inside diameter of 5.7cm) and thickness of 0.33 cm is placed around the protruding core. It operates at 120 V(rms), 60 Hz household ac.© BrainMass Inc. brainmass.com October 25, 2018, 7:51 am ad1c9bdddf
Magnetic flux density B is produced by a solenoid wound, with n turns per unit length and current I passing through. It is given by: B = ?0?rnl (1)
This is where ?0 = permeability of free space and ?r = relative permeability of the core.
Furthermore, ?r = 1 + ?m = 1 + 10 = 11 (The susceptibility ?m of the core is given as 10)
The voltage applied to the solenoid is 120 V (rms), 60 Hz. Hence, the peak voltage is V0 = ?2 x 120 = 169.7 V. The applied voltage V = V0sin(2?f)t = 169.7sin377t. The magnitude of current I, through the solenoid, is ...

Managing in a Cross-Cultural Environment in global business
See attached files.
Question: When conducting business globally, managers often must modify their strategic approaches in the course of conducting business in different countries. Identify a situation where this would be the case and discuss the steps you would take to ensure that your team was prepared for cross-cultural interactions in this situation.
Question: Cultural 'mishaps' do occur in the process of conducting business on a global level. Oversights, when considering cultural norms and values in other countries, have caused public embarrassment to numerous companies. Identify an example of this and discuss different alternatives that could have produced other outcomes.View Full Posting Details
