Electromagnetic Induction and Alternating Current 1 Question 17
####17. A current from $A$ to $B$ is increasing in magnitude. What is the direction of induced current, in the loop as shown in the figure?
$(1979,6 \mathrm{M})$
Show Answer
Answer:
Correct Answer: 17. Clockwise
Solution:
- Magnetic field due to straight wire passing through the wire loop will be perpendicular to paper outwards. With increase in current in straight wire, outwards magnetic field through the loop will increase. Therefore, from Lenz’s law, inward magnetic field will be produced by the induced current. Hence, induced current is clockwise.
