Magnetic stored energy density for iron is given by ______

Magnetic stored energy density for iron is given by ______ Correct Answer 1/2 B2/μ

Magnetic stored energy density for iron is given as wfld=Wfld/((Length of the magnetic path through Iron)*(Iron area normal to the magnetic flux))=1/2 (F∅)/(length*Area)=1/2 F/length ∅/area=1/2 H*B Also, H = B/μ,thus wfld=1/2 B2/μ.

In the following question, the first and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R, S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. S1. Energy conservation refers to the efforts made to reduce the consumption of energy. P. Furthermore, energy can take plenty of time to regenerate. Q. The energy on Earth is not in unlimited supply. R. Most noteworthy, energy conservation is achievable either by using energy more efficiently or by reducing the amount of service usage. S. This certainly makes it essential to conserve energy.  S6. Energy conservation will reduce the expenses related to fossil fuels.

Modern civilization is completely dependent on energy, which has therefore to be abundant and also economical. About 85% of the world's energy is supplied by oil, coal and natural gas while nuclear, hydro, wind and solar power and biomass supply the rest. Coal, nuclear and hydro are used primarily to generate electricity while natural gas is widely used for heating. Biomass is used both for heating and cooking. The wind and solar power is the future's hope as they are sustainable energy sources. Oil powers almost all machines that move and that makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are ubiquitous. Clearly, we live in the age of oil but it is drawing to a close. According to data available if oil production remains constant until it's gone, there is enough to last 42 years. Oil wells will produce less as they become depleted, which will make it impossible to keep production constant. Similarly natural gas and coal will last another 61 years and 133 years respectively. Naturally, as they become scarce, they become expensive, leading to a worldwide energy crisis. If we are to survive on this planet, we have to make a transition to sustainable energy sources. The transition may be willy-nilly or planned - the choice is ours. The dawning era of limited and expensive energy will be very difficult for everyone on earth but will be even more difficult if it is not anticipated. It is of utmost importance that the public and policymakers understand the global energy crisis and act in tandem to ensure that the species 'homo sapiens' does not become extinct.
