Calculating Inductance and magnetic energy … please?
The magnetic energy stored in a certain inductor is 2.00 × 10-2 J, if the current is 5.00 × 10-2 A. Calculate the inductor. What is currently needed for the stored magnetic energy to four times as much?
Your's are even lighter than mine … Ub = 0,5 i ^ l 2L = 16 L thn keep the same increase of Ub 4 and solve for current .. You should now have a 0.1 A

I have some information that you’re going to love! There is an information product available on the internet that will explain how the average homeowner can build and install their own independent power source and achieve complete energy efficiency! We’re talking about a magnetic power generator that creates zero cost electricity, and doesn’t rely on mother nature (ie. wind or solar energy). When installed and functioning, these magnetic generators create their own energy and they’ll power your home for free! Plus…you may be eligible for residential renewable energy tax credit!
