Explanation
An electron beam is moving near to a conducting loop then the induced current in the loop:-
As shown in the figure, a magnet is moved with a fast speed towards a coil at rest. due to this induced e.m.f, induced current and induced charge in the coil is e, i and q respectively .if the speed of the magnet is doubled , the incorrect statement is:
Given that,
Average emf V=20V
Current i=2.5A
We know that,
V=LdIdt
20=L×50.1
L=2050
L=0.4Henry
Hence, the self-inductance is 0.4 henry
