标题[问题] Stacking factor...
时间Wed Jan 14 23:35:59 2009
A laminated section of core has cross-sectional dimensions of 0.03m by 0.05m
and a staking factor of 0.9.
a. What is the effective area of the core?
b. Given Φ=1.4*10^-3Wb, what is the flux density, B?
请问这题到底是在叙述甚麽东西??
还有Stacking factor 又是甚麽??
麻烦高手帮忙一下!!
