Question

find self induction for a circular coil​

Answer 1

Answer:

here is your answer

Explanation:

There's a formula for self inductance :

L=nΦi

where n is the number of loops.

But the book also says self inductance is directly proportional to n2

I totally agree with the second sentence. But the formula seems to show L is directly proprtional to n and not n2.

Answer 2

Answer:

If i = 1amp, N = 1 then, L = ϕ i.e. the coefficient of self induction of a coil is equal to the flux linked with the coil when the current in it is 1 amp. 3) By Faraday's second law induced emf e= -N dϕ/dt. Which gives e= -L di/dt ; If di/dt=1 amp/sec then |e|= l
