i made core out of Mu metal strips (μ=0.01) to make a transformer, but surprisingly instead of giving higher emf due to its higher permeability it gave poorer results than a laminated iron core....what might be the reason..please help.
1. it does, but higher permeability should give higher magntic intensity thereby higher flux followed by higher emf for the same number of primary and secondary turns, B ( For a solenoid )= (μ.N.I)/LI have some questions:
1. Doesn't the no load EMF of a transformer depend on the turn ratio,
and not the mu of the core?
2. How does the mu of the mu metal compare with that of the iron?
3. How does the hysteresis curve of the mu metal compare with the iron?
If it is fatter, it would have less efficiency.
