There are two coils A and B seperated by some distance. If a current of 2 A flows through A, a magnetic flux of `10^(-2)` Wb passes through B (no current through B). If no current passes through A and a current 1 A passes through B, what is the flux through A?

Text Solution

Verified by Experts

From `phi = MI, M = (phi)/(1) = (10^(-2))/(2)` henry. Again, from `phi = MI = (10^(-2))/(2) xx 1 = 5 xx 10^(-3) Wb`

There are two coils A and B separated by some distance. If a current of 4 A flows through A, a magnetic flux of 2 X 10^(-2) Wb passes through B (no current through B). If no current passes through A and a current of 2 A passes through B, what is the flux through A?

Two coils A and B are separated by a certain distance. If a current of 4 A flows through A, a magnetic flux of 10^(-3)Wb passes through B (no current through B). If no current passes through A and a current of 2 A passes through B, then the flux through A is.

Two coils 'P' and 'Q' are separated by some distance. When a current of 3A flows through coil 'P' a magnetic flux of 10^(-3) Wb passess through 'Q'. No current is passed through 'P' and a current of 2A passes through 'Q', the flux through of 'P' is :
