Question
A coil consists of 100 turns of wire in shape of circle placed in the y-z plane. The loop has an area of 1m2
Two magnetic fields linking the surface of the loop:
The first one is given by: B1 = –10t²
The second one is B2 = 20isin(2w)t
Find vtr
emf
Select one:
O a. vtr
2000t – 4000.w.cos(2w)t
emf
O b. 0
O c. vtr
emf
= -20t + 40.w.cos(2w)t
O d. vtr
-2000t + 4000.w. cos(2w)t
emf
O e. vtr
emf
20t – 40.w.cos(2w)t
O f. vtr = 20t
emf
O g. vemf
- 40.w.cos(2w)t
