(I)=((N*pi*r^2)/R)*dB/dt
N=number of turns
r=half your diameter in meters
R=the resistance
dB/dt=is the derivative of the field in relation tot=.02+.02t
I(t) =.025{cdot}{pi}{cdot}left(.02+.02tright) rm A
According to Faraday’s law, the relation between the induced emf and magnetic field is given as: dt -Nd(B.A) dt Here, D is the magnetic flux induced, B is the magnetic field and A is the area .d(B A dt d(В-А IR -N dt Rearrange for I as follow: ,d (В-А) 1 -N I dt R d(B) -N A dt d(B -N dt
The magnetic field acting is time differentiated: d(B) N (A) dt I R d(0.020+0.010) N (zR)| dt R d(0.02t+0.0102)T 20 (7(2.5×10 m) dt 0.5 0.0785(0.02 0.02t) -0.00157 (1+)A The current is expressed as: 0.00157 (1+t)A
