construction interference is when you build things up and destructive interference is when you tear things down
Answer:
(c) keeping the orientation of the loop fixed and moving it along the field lines
Explanation:
Ampere's Law current is calculated by evaluating;
∫ B. dl
Here B= magnetic field and dl- length segment in which current is to flow.
Clearly as magnate field lines are perpendicular to the plane of loop having some length ==> dot product will be zero for 90 ° angle and hence current will be zero in the loop i-e we will keep the position of loop and move it along field lines !
Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field.
Electromagnetic induction has found many applications in technology, including electrical components such as inductors and transformers, and devices such as electric motors and generators.
Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Lenz's law describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell–Faraday equation, one of the four Maxwell's equations in James Clerk Maxwell's theory of electromagnetism.
